how will coby be a toptier tho
He has CoC lol.
He has kingly ambitions -> become navy Admiral and somehow close the gap between him and Luffy, something seen as impossible but both Luffy and Zoro recognizing that Coby and Helmeppo Will be formidable enemies.
As Luffy said "I am way stronger than you Coby and I will keep growing stronger from Island to Island, but you want to become a navy Admiral, you want to capture the pirate King right?"
Coby was like "I want to follow his footsteps but it's impossible"
"I know Coby can do It!"
Will Is All in One piece.
If Luffy has Faith in Coby you should have Faith in him too, actually you should be scared because EOS Helmeppo, Coby 's right hand man might be a challenge for EOS WSS Zoro.
