They still need a doctor I suggest Hanafusa from Kengan I feeling that psycho would fit right in

He still technically needs a proper chef on his crew I suggest Komatsu from Toriko

If you want a digimon I suggest either Renamon or Meicrackmon

If Aqua gets stronger I think it'd be a good idea if her blessing had the ability to remove a devil fruit users curse so they can swim

Charmander is honestly a bad choice since it's horrible against the first two gyms

He should definitely learn Rokushiki it suits him perfectly he's literally a leopard

It's crazy Yoruichi isn't on the list even though she's on the freaking cover

For the next world I'd recommend OG Dragon Ball with Kid Goku I feel like there would be a lot you could do with that

Thunder Punch is basically useless on Abra it has zero physical Attack

I'm sorry, but did he just pass on picking Lord Helix!!!
