Who has the most powerful enlarger quirk, Yui Kodai or Mount Lady? According to the My Hero Academia Wikia Mount Lady can enlarge to 20,62 metres. In the other hand, it's shown in the anime Yui Kodai can also enlarge herself. Is it known how much can she enlarge? Who has the most powerful enlarger quirk, Yui Kodai or Mount Lady?
We don't know how much Yui can enlarge herself. However, there are two distinct points that make their quirk different.


Mount Lady only enlarges herself to 2062 cm. That's it. However, Yui can change her size as she wants. If her quirk has no limits (again we don't know) she might overgrow Mount Lady.
Yui also shrinks herself but that's not relevant for the question.
