Chest Hair is the Quirk used by Tenma Nakaoji.
Description#
Not much is known about Chest Hair, but due to the nature and name of the Quirk, it presumably enhances the user's masculine traits.
While it's unknown if related to his Quirk or not, Tenma also seems to have enhanced strength and possibly the ability to emit purple lasers from his nipples, however the laser nipples could simply be an adaptational choice to display Tenma's enhanced masculine traits in the anime.[1]
