Statistics Amplification

Summary
Stat Amping is when a character raises their parameters in the middle of the fight that is not found to their base form or some sort of "hidden power" that has been hidden or held back. These boosts are usually temporarily and are specific to one or a number of stats. This also not to be confused with a change in form or state, and is thus not typically associated with any new abilities in particular. Instead, they serve as a means of overcoming the opponent through a sudden increase in combat effectiveness. This ability is very common in video games, but is still prevalent in other works.
