Ocean God it looks like? Reminds me of this story from /TG/. A player had a pure good weakish fisherman in a game where everyone is supposed to be kinda evil.
Anyway, so fishman and team (who bullied fisherman the whole time, because pure good) go to fight the BBEG, whose plan is to increase his evilness to infinity levels.
Party fails, BBEG becomes infinitely evil, but fisherman pulls some shenanigans. He uses an ability that only pure good character can have that increases his water-based power multipled by any surrounding evil.
Fisherman becomes >>7195775
and fucks all the bad things. Wish I had the proper story
