Hi, I'm Oswei! I study the supernatural phenomina of the world! Things like Monsters and Esper! I want to know how and why they work the way they do!
~ Oswei before his monsterfication
How does it feeI, Miro? You never believed you'd encounter someone with better control over fire than you, did you? I hope it hurts, because I am the The Flammosaurus Rex!! And I am the monster of your dreams, the one you've always wished would appear, the one you wanted to protect your village from! Because all you've ever wanted is to have your little ego stroked, correct...? Well, hear me now, Firestorm... I am Oswei. I am your victim. And now... Your executioner!!!
~ Oswei after confronting Miro at Dark Forest Village
All I ever wanted to do was the right thing. I came to your village because I wanted to understand. Your power, the ability to wield the elements, was extraordinary... And I wanted to know everything I could. I went to your village, Miro, and I received a warm welcome which I truly appreciated. I know how your family views outsiders. But, in your childish arrogance, ou murderdd a monster in the forest, and I was there to bear witness. You intentionally unleashed an overwhelming flame which decimated the surroundings. I Was trapped in that inferno, and from that fire, The Flammosaurus Rex was born... Oswei ceased to be... But you, Chitan, and my dear sister have shown me the error of my judgement. I would love to join you in your new lives, but I have done far too much, committed too many sins, destroyed too many lives. I can't show my face to the world with a look of pride, knowing that my victims shall forever scorn me. I made them feel small, as you had made me. That's why I have to do this, however you must promise one thing: Do not ever use your power without sound judgement. Your power is incredible, and with incredible power, you must also bear the consequences of it. To be the hero you truly long so much to be... Don't ever forget what happened to me. Take those feelings of guilt you felt, and turn them into a passion for protecting the world!
~ Oswei's redemption before sacrificing all of his power

Summary[]

Dr. Oswei Atami was a scientist who specialized in Monster Biology, a very rare type of science which not many practiced. Oswei was always interested in history and the unique powers which seemed common throughout the world, in both humans and monsters. He loved to travel and research various places of greats significance to the past, present, and even future. He used his historical interests to cope with his loneliness after most of his family had died in a massive fire, with he and his sister only surviving because of their pure willpower, with the burn scars reminding them both every day of what happened. Later, he got wind of Dark Forest and went there because their power intrigued him, and he wanted to know more.

The people of Dark Forest are led by the Fennbirn family. The eldest child always had triplets, and those children would always inherit three powers which were spread amongst them, the most powerful of which being the ability to wield elements, which supposedly hadn't been seen for generations. When he arrived, he was greeted by Leonora and Genevieve Fennbirn, who gave him a warm welcome (although Genevieve was quite nervous that he would discover their "secret"). He was allowed to stay for a couple of days, and on the last day, he wandered the forest around the village, studying the plants and fauna of the area. However, nearby, a ruthless monster appeared and proclaimed its desire to annihilate Dark Forest. Miro Fennbirn, the first elemental in generations, pledged that he would use his 'awesome' fire to protect everyone. He destroyed it with his fire, but it was out of control and annihilated Oswei too, who Miro had no idea about.

Oswei's vocal cords were burned quickly. he had to watch himself melt, and couldn't even scream. After surviving an inferno once, he was now forced to die by the out of control ego of a little kid. At that moment, he remembered just how small it made him feel to be utterly helpless to avoid the fire, and he felt a fury unlike that he ever could have imagined, and he become a tyrannosaurus monster made entirely of *flame*. Now forced to live as the very thing which had ruined him, he cursed his new existence and hid away inside a deep cavern all the way by outskirts of Z-City, where rumors would spread of a dinosaur made of fire occasionally lighting the night. Thunder Dragon heard the rumors himself and sought the answer, eventually plunging deep enough into the cave to find Oswei. He promised revenge on Firestorm, so Oswei was quick to join, as he also believed that killing Miro would avenge everyone else he loved who perished in flame and maybe even provide him the opportunity to see his sister. From then on, he was officially a Terrorblite, and one of Mars' four guardians alongside Alva, Daiki, and Clarissa.

Powers and Abilities (Great Sea War Arc)

  • Large Size (Type 0; taller than Alva, and similar to a real T-Rex. Even larger in Humanoid form)
  • Immortality (Type 3; a regenerate as long as his body is 'burning'. He can recover from damage which blows him apart, because his fire would still remain)
  • Enhanced Senses (Oswei can detect heat signatures from the air. He can sense the movement of the Earth's mantle and is even capable of reacting to things around him in his sleep. His senses are comparable to Clarissa, Alva, and Daiki)
  • Natural Weaponry (Teeth and claws. In his humanoid for, his claws are far more prominent)
  • Energy Absorption (Oswei can absorb energy attacks and fire attacks to make himself more powerful)
  • Fear Manipulation (When others look into his eyes, they are instantly made to feel unnerved. Even other powerful monsters like Alva felt nervous when he glanced at her)
  • Heat Aura (Oswei constantly emits a passive aura of up to 1000 degrees Celsius, which he can make even hotter by focusing/getting angry, allowing him to melt almost anyone who dares approach him
  • Smoke Manipulation and Telekinesis (Can create fiery clouds of smoke which can lift things into the air or use them to lift himself. Lifted Dark Forest Village into the clouds with them)
  • Temperature Manipulation (Oswei can alter the temperature around him to be far hotter with his heat aura, though he can also 'vacuum' the heat from the air around his opponents, making it freezing cold and trapping them in ice)
  • Breath Attack (Oswei loves to launch his beams and fire attacks directly from his mouth when he is in T-Rex form. He still does so in humanoid form, but largely switches to his hands)
  • Air Manipulation (Oswei can create dozens of flaming tornadoes which slash through opponents)
  • Light Manipulation (Oswei can unleash horribly blinding light potent enough to even affect those with closed eyes. Alongside that light are often waves of thousands of degrees of heat)
  • Explosion Manipulation (Oswei can blast pure explosions from his mouth, as well as fireballs that violently explode on contact)
  • Danmaku (Oswei is capable of launching up to 10,000 fireballs all within a few moments)
  • Body Control (Oswei can control the fire of his body to avoid burning everything around him at all times. He could control his heat so that he was able to grab Kellen and Arsinoe without instantly melting them)

  • Regeneration (Mid-High; can regenerate from being completely blown away, and even from pure smoke itself)
  • Immunity to Heat based attacks (Oswei cannot be hurt by fire, even if that fire is hotter than his own. It's simply absorbed into him, making his flames all the more stronger)

Powers and Abilities (Flame Titan)

  • All previous greatly enhanced
  • Blessed (Received a blessing of power from Queen Shinigami)
  • Transformation (Can disguise himself in his human form, the one from before he monsterized, and transform into the Flame Titan by yelling "This is my fire!")
  • Magistream Magic (Thanks to Queen Shinigami, Oswei's body is made of magical flames called Titan Fire. Although it is not 100% magic, there are other magic fires in him such as Soulfire. Thanks to this, he is highly resistant to non-magical attacks and can devastate those without it)
  • Corruption (As a 'Blood Warrior', Oswei's mere presence corrupts and ruins everything within his vicinity. Humans and Monsters who get too close to him transform into Blood Soldiers and obey his every command. Only a Sapphire Soldier can avoid the corrupting aura)
  • Hellfire Manipulation (Titan Fire partially consist of Hellfire, a type of magical flame which burns far more intensely than the universe usually allows)
  • Extrasensory Perception (Can sense when someone has been blessed to be a Sapphire Soldier. Can detect the feelings of others and what they may be thinking)
  • Large Size (Type 3; exactly 1200 meters tall. He towers above the buildings in all of the cities except for Hero HQ itself and is able to peak over large mountains without stretching. Every step generates a large rumbling)
  • Weather Manipulation (Oswei's mere presence alters the weather within 100 kilometers to be that of somewhat stormy, however, the storms are that of fire, not rain)
  • Portal Creation and BFR (Oswei can open portals that lead to the Sea of Blood, and can use them to banish enemies to the Sea of Blood prison, which cannot be escaped without holy magic)
  • Transmutation (Titan Fire can transmute incoming attacks into pure heat, empowering the fire and allowing Oswei to avoid damage altogether)
  • Gravity Manipulation (Titan Fire can alter the gravity around it, drawing opponents into it to be smelted. It can also curve gravity to interfere with the trajectory of incoming attacks, forcing them to dodge even if they are supposed to e homing in on Oswei. The gravity changes can also be used to slow opponents speed)
  • Radiation Manipulation (Titan Fire, by its very nature, is radioactive. The radiation around it is enough to infect the land Oswei walks on for thousands of years, and instantly kill or mutate most who are close to him. Alongside his heat, however, he is able to control its output)
  • Matter Manipulation (Can use Titan Fire to create a field that disintegrates an area and everything within said area down to and beyond atoms)
  • Healing (Can use Titan Fire to restore the wounds of others by taking the place of their 'broken parts')
  • Soul Manipulation and Durability Negation (Titan Fire is partially formed from Soulfire, which can burn away souls. It can bypass armor and barriers to instantly incinerate opponents)
  • Sound Manipulation (Oswei can unleash a piercing scream across the globe which forces an innate reaction from Blood Soldiers, drawing them in from afar to assist him in battle)
  • Summoning (Can summon Blood Soldiers with his screams)
  • Creation (Can create 'fire warriors' to aid himself alongside the Blood Soldiers. The Fire Warriors are humanoid and stand at 20 meters tall. Since they are made from Titan Fire, they each possess all of the resistances that Oswei does)

Attack Potency: At least Moon level, Planet level when enraged (Comparable to Alva, Clarissa, and Daiki. Stronger than all of the Terrorblites which agreed to separate from Mars alongside of him, as he acted as their leader, with even Clarissa fearing him and his wrath. Instantly incinerated all of T-City while casual, and dominated post Dragon Heroes Miro. Alva was unsure that she'd be able to stop him with Death Mode if he was angry enough. Fought with and overwhelmed Chi and Nephilim. Went toe to toe with Mars for a short period of time), Higher with Lusca's enhancements (Grew stronger than before. Easily batted Nephilim around without even using his anger) | Multi-Solar System level (Comparable to the Bloodborn, though as a Blood Warrior, he is weaker than them. Was able to fight against multiple 'Blessed Ones', including Miro. After turning away from the Sea of Blood, he went toe to toe with the 'Ice Titan' King Titan Bug, and was able to destroy him after an extended battle, though at the cost of his own life later), Higher with 'Titan Core' (With his Titan Core, he was able to inflict massive damage to King Titan Bug. The Titan Core pushes his power to its absolute limit, allowing him total access to the power of his anger, though also allowing him to maintain a level head. His core surpassed that of King Titan Bugs')

Speed: At least FTL (Faster than all of the Terrorblites sans Mars and Alva. He's faster than Clarrisa, who blitzed Helios pre-magic, and easily outpaced Miro. Kept pace with Chi and Mars and even surpassed them at times) | Massively FTL+ (Comparable to the Bloodborn. Matched speeds with Miro post-blessing while fighting off other threats from the heroes as well. He was near equal to King Titan Bugs speed until surpassing him thanks to his sister's encouragement)

Lifting Strength: At least Class P (Comparable to Alva) | At least Stellar (Far higher than before. Titan Fire carries the weight of stars, and Oswei's entire body is made from Titan Fire. He supports himself with no issue)

Striking Strength: At least Moon level, Planet level when enraged, Higher with Lusca's Enhancements | Multi-Solar System level, Higher with Titan Core

Durability: At least Moon level, Planet level when enraged (Comparable to Alva. Took attacks from Mars, Chi, and Nephilim), Higher with Lusca's Enhancements (The same attacks which had previously hurt him now had no effect) | At least Multi-Solar System level (Took attacks from multiple Blessed Ones at once, including Miro. Survived King Titan Bugs ice attacks which were stated to be capable of 'snuffing out the night sky)

Stamina: Superhuman (Comparable to Daiki and Clarissa. During his final battle with Miro, he used all of his attacks, but still didn't get tired. As long as his fire burns, he will continue to battle. His stamina is far higher when he becomes the Flame Titan)

Range: Extended melee range via size, Hundreds of Kilometers with blasts | At least Planetary (His blasts could be easily launched around the world), likely Multi-Galactic (Should be comparable to the Bloodorn, who's influence stretched beyond the galaxy)

Standard Equipment:

  • None notable

Intelligence: Genius (Before monsterizing, Oswei was a genius scientist who was extremely knowledgeable on monster physiology. Oswei is behind the modern "theory of monsters", which shows the inner workings of Mysterious Beings, their mental states, and the natures of their DNA codes. The Theory of Monsters, ironically, proves that there are certain monsters which are not entirely evil by nature, despite the continuing evidence stating otherwise, thanks to the examination of monster mental capacity. His studies were beyond what many of the worlds most esteemed scientists were capable of at the time, although his study was largely censored for its radical take. He maintained this intelligence following his monsterfication, though his brutish and angry nature brought others to believe he was much less intelligent. He continued to use his intelligence to form schemes and fight his battles, changing strategies mid-fight and wielding his powers in creative ways to trick and talk advantage of opponents)

Standard Tactics: Oswei angrily attacks his opponents, using his fire to outright destroy them. Using his intelligence, he's changes his strategies according to his opponents battle styles, though he can be impatient with such tactics.

Weaknesses: None notable | His core can be exploited by the right abilities

Notable Attacks/Techniques:

Transformation: Oswei can transform into a more humanoid form which allows for better hand-to-hand combat, as his 'real' form has arms like a T-Rex. He's faster in his Dinasaur form.

Regeneration: Oswei is capable of regenerating when his flames are blown apart, even if he's left as a small fireball. However, this power can be negated if someone 'stripped' his fire from him. As the fire would no longer be part of him, it would no longer regenerate. This can be done by those who can directly manipulate 'pure fire', as in fire in its most natural state.

Flame Power: Oswei's power largely comes from fire. He can manipulate flames masterfully, to the point of even being able to wield magma, pure heat, beams, and much more. Most of the tie, he fires attacks from his mouth, however, in his humanoid form, he uses both arms to launch extra moves.

  • Flame Clouds: Oswei create fiery clouds of smoke which can lift things into the air or use them to lift himself. He can spawn them like stairs in the sky and expand them enough to carry large stretches of land right into the sky.
  • Hell Tatsumaki: Oswei spews multiple tornados of blazing flames which surround, then raze his opponents with hundreds of slashing winds which carry his fire all across the battlefield, and swirl all around. The tornados forcefully vacuum others into them, and once trapped, they are thrown about, alternating through the tornados until they've been sliced to nothing. Once the attack is over, the entire area is consumed by the passive flames of the fiery wind.
  • Wrath Volcano: Oswei throw his head to the sky and an eruption from his mouth occurs. Thousands of fireballs fly through the sky, then collapse down like meteors. As each one crashes, they create gigantic explosions and cast out shockwaves. They grow stronger and larger with Oswei's rage.
  • Heat Vacuum: Oswei 'vacuums' the heat from both the area around him and his opponent, freezing them both, as there is no longer heat for them. With this, Oswei can trap his opponent in a shell of ice and hat their bodily functions.
  • Solar Wave: Oswei casts a powerful shockwave brimming with light from his mouth. It both blinds and decimates scores of opponents all at once with thousands of degrees of heat. The light is so bright that even those with covered eyes are affected.
  • Tyran Reflection: Oswei creates a bursting wall of fire around his entire body which reflects incoming attacks. His fire infuses itself with the reflected attacks, making them up to three, sometimes four times as powerful. If the reflected attacks are fire based, they combine with the barrier, and Oswei is made larger and stronger.
  • Vengeance Firestorm: An attack named from Miro's hero name. Oswei summons a hurricane of flame which devastates everything within its extensive range. The flames incinerate opponents incoming attacks, and they 'rain' fire droplets, which are much more akin to bullets, which destroy everything in their wake.
  • Vengeance Gaia: Oswei's 'ultimate move'. Oswei wields all of his flames, then begins to gather energy from the very Earth itself, causing an intense rumbling, natural disasters, and the opening of massive chasms around him, from which lava erupts. Then, all of the energy localizes into his mouth, and he fires a vast beam of searing magma and pure flame to obliterate his opponent right in their tracks. The beam is able to reach beyond the moons orbit at full power.

Heat Aura: Since he's made of fire, Oswei constantly emits a passive aura of up to 1000 degrees Celsius, which he can make even hotter by focusing/getting angry, allowing him to melt almost anyone who dares approach him. The aura is hot enough to melt shards of glass from Mikio.

Lusca’s Enhancement: With the enhancement provided by Lusca, Oswei's defense goes up by a significant amount. He gains even better control over his fire and becomes slightly stronger overall as well.
