Not sure if he fits but Ephemeral Oma Zi-O is pretty smart. He's Extraordinary Genius btw, particularly in temporal matters and Temporal-Tech. The only reason why he isn't Supergenius is because he shows visible gaps in his knowledge; while he isn't a complete novice, he does not have a mastery over combat forms (Not that he really... needs it), he finds biology difficult as there will never be a guarantee of an answer unlike with mathematics and such, Magic (Which is a Science in his Universe) is also an area he lacks proper understanding in despite it being fairly commonplace, and Void Energies (Which is particularly major) eludes even him due to its exotic nature.
 * Invented the Jiku (Space-Time) Driver to be used for Kamen Riders who utilize Ride Watches. The closest "Scientific" Name for the Jiku Driver is a Quantum Manipulator which manipulates Quantum Fields to project the Rider Suit.
 * Implied to have invented Ridewatches, devices which steals and stores the history of something (So for example, if you were to steal the History of WW2, it would cease existing in this Timeline and all events directly pertaining to WW2 will be stored in the Ridewatch)
 * Created a Composite Ridewatch known as the GrandZi-O Ridewatch which is an amalgamation of every Heisei Rider's Histories
 * All of his personal Ridewatches has the ability to affect Time to furthering degrees; Zi-O Form is able to steal time while Zi-O II is able to outright rewrite history and GrandZi-O is able to rewrite entire Timelines
 * Oma Zi-O's suit, built by Sougo, is able to manipulate Causality and control the Existence/Nonexistence of things
 * Made it so that Oma Zi-O, the power, is a Temporal Constant via extreme trickery and manipulation. For example, even if the entire history of Oma Zi-O ceases to be (as in the case with the canon Zi-O Finale), even though the power proper is gone, Sougo would've made it so that in the new History (or Histories), the new Sougo (Or equivalent) would inevitably gain the powers of Oma Zi-O once more. The method he does this is unknown however, so take this with any grain of salt you wish.
 * Has an acute understanding of Dimensional Walls, the thing separating Universes. His understanding is at such a level that he is able to traverse between Universes and prevent others from doing the same which normally shouldn't be possible
 * Has a masterful understanding and control (As Oma Zi-O) of Time Gates; the highest level of Time Manipulation one can have. These are doors which ties all Timelines together throughout the Infinite Multiverse. To emphasize how impressive this is, natural 4D Civilizations are completely unaware of the existence of Time Gates let alone the manipulation of them.
 * Has a strong grasp on Psychology, playing other people and deceiving them for years or even lifetimes at a time with little to no suspicions
 * Has a respectable understanding of the Afterlife and Spirits, being able to create bleeding edge technology to trap and later, outright destroy them. This understanding allowed him to integrate Principality Form into Zi-O II despite them normally being mutually exclusive.

Also being able to become a 6D God sounds 100% Supergenius to me :L
