The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
probably a subtrope Antagonist Abilities.
It most certianly belongs there but I can't seem to find a specific call out to it.
Ignore this reply

The villain is revealed to be able to use the same power as the protagonist which negates their advantage/plot armor or is revealed to be able to bypass it or work around their signature ability/technique with an inverted version. Its not just that the antagonist is immune or has an ability which impedes the hero. It must be in direct relation to the hero's ability. This is also seen in reverse where the hero is able to utilize the power of the enemy.
Some examples: Jotaro having the same stand as Dio negating his time stop power advantage, Moriarty being able to pre-calculate a fight just like Sherlock, Beta Ray Bill being able to wield Mjolnir just as Thor can.
