Muscle Enlargement

Muscle Enlargement is a Quirk possessed by an unnamed Artificial Human that battled Enji Todoroki and Gran Torino. It is also possible that the Quirk was formerly possessed by All For One.

Description
The Quirk allowed unnamed Artificial Human to enlarge his muscle structure and heal damage caused by absorption of Todoroki's flames, before shrinking back to his original size.

The Quirk was demonstrated just once and never described closely, causing the uncertainity around its capabilities and relation to Tongue Web.
