Growth (成長, Seichou) is an ability Hit has when facing an opponent stronger than he is, allowing him to imprint on his new battle experience to quickly adapt and increase in skill. It is only displayed in the Dragon Ball Super anime.
Growth increases Hit's Time-Skip ability. When Hit first grows, his Time-Skip doubles, allowing him to intercept Super Saiyan Blue Goku's attack, and upon increasing to half a second he is able to overwhelm him thanks to the length of the Time-Skip. Then when Goku uses the Kaio-ken x10 on top of his godly form, Hit manages to further grow so that he can freeze things that manage to move in the Time-Skip, allowing him to dodge Goku's match ending blow. His improved Time-Skip then allows him to fight on par with Goku when the latter's Kaio-ken drops back to x2, though it is noted that the match could go either way at that point since Goku still held a power advantage.
