Dude. Ricardo is basically a better Mihawk.
The "I'm bored and alone at the top" "I'm waiting for someone worthy".
How he's introduced, how he completely outclasses Ippo on their sparring, how he beats Eiji, how he gets developed later on, etc.
Seriously.
Everything about how Ricardo is written and presented is better than how Mihawk is.
We actually get to see Ricardo giving justice to his title of champion. Mihawk is another case of "people say he's the stronger", but we only see him fighting fodders and an overconfident East Blue Zoro.
Oh yeah. He cuts a piece of ice in an arc where people are creating cataclysmic events.
Wow.......impressive.....
Doesn't help the fact that Oda holds him back so much and he gets stronger automatically due to the normal power creep of the story.
