you had an alliance with the Strawhats

So, Luffy is an idiot, wanna know why? Because he was playing with Usopps experimental stuff and somehow turned himself into his past self; his child version. Usopp was standing next to you

Usopp: how did he...?

Luffy was running around the ship; Thousand Sunny. Running away from Zoro who was trying to catch him

Zoro: Luffy! Come back here!

Luffy: NO! AND HOW DO YOU KNOW MY NAME?!
