Acanos kinda like a mixture of Goku and Vegeta the more I think of it
He's goofy, finds battle extremely fun, only really gets truly serious about it if someone he cares for is actually in danger. He can be reckless, and kinda dumb sometimes, not always thinking things through but always having the best intentions at heart. He always tries to be the best partner and father he can to Erina and their kids, he's not perfect in the slightest but he's not bad at all either.
On the other hand, he can become angry easily if he feels like someone's insulted him, his family or his species. He can be overconfident in his abilities and that can lead to needing to call in Erina for help. He's protective of his Wife despite knowing her strength. He's got a prideful side that can and does take over sometimes, particularly after he's won a lot of battles. He's convinced he's one of Everemths best warriors, that he's near unbeatable in the ring because the only person who managed to defeat him is now his wife. Hes absolutely enamored with her, in fact.
I didn't have either of those two in mind when making him but its kinda fun seeing what characters had their traits unconsciously sneak their way into his personality
