I'd honestly love to have Caesar on the crew lmao. He's been on the same journey for a very long time like Kin and Momo. He can't just disappear like that.
The greatest Scientist, future opponent of Vegapunk, gas logia, has a goal and real purpose.
He doesn't have side character design like garbage rabbit and he's actually funny. Would fit in the pervert trio with Sanji and Brook. Motherfucker is a real gangsta
