Honestly, he feels like Broly if he was a canon character of the original Dragon Ball manga. A great part of Broly's popularity that set him apart from all other filler villains is how intuitive the idea behind him felt, like it would easily fit into the main story. Koku is like that. The idea of him feels like a fanfic, but it also makes you think "of course there's a character like that in this type of story".
