I get that you’re trying to say the raid suit, basically has a devil fruit ability. I was thinking a zoan. Special one too. Mythical I guess.
My favorite choice being a hellhound. Since Sanji’s abilities seem to be based on his previous opponents, it would fit from facing jabra (although he has geppo). Camoflauge should definitely be more of an enemy skill. Either way it would be a great power-up. Sanji should be matching up with the supernovas and stronger guys by now. Him being a dog or something wouldn’t take away from his fighting.
The thing is, Sanji so far is the only character I know who can fight in 3 different terrains (underwater, land, sky) without losing his speed, without depending on any devil fruit,having to spend haki & transform to Gear 4 like Luffy.
Versatility & mobility are what make Sanji crazy dangerous now. And now he can go invisible as well? Are you kidding me?
In MOBA, it's like having a carry who's tanky, mobile, who can initiate fights, pick up kills, and escape easily. I'd pick Sanji as my carry all day.
As far as I'm concerned, he can just go invisible, kick ass from many blind spots & the enemy can't even answer before they turn into corpses.
I would even label Sanji as the
natural enemy of almost every single fruit user in existence in naval combat.
With his speed, durability, stealth mode, swimming, all he needs to do is carry his opponents to the sea & drown them.
And he can do that while cooking for Luffy in Thousand Sunny if he wishes so.
If the enemy doesn't have either of very high level of observation haki-speed-endurance, they will probably get slaughtered by Sanji.
And even if Sanji can't win against some powerhouses & certain abilities,
Sanji is also unbeatable against most people.
And note that I'm not even a Sanji fan, more of a Zoro fan.
