One For All is the central inherited Quirk in Kohei Horikoshi's My Hero Academia, serialized from 2014 and adapted as an anime from 2016. Passed from holder to holder, it stockpiles raw power, most famously used by Izuku Midoriya after receiving it from All Might. Charge up effects linked to the Quirk spread through anime edits, fan videos and soundboards as a shorthand for building strength. Its short rising format made it easy to reuse across platforms, and it remains popular for heroic buildups and parody power ups alike.
