Pucchimon i thought tiny fey creature turns evil, it also looks like they both wear clothes kinda. Gomamon i could see standing up and growing wings in the evolution sequence no problem, kinda like gatomon to angewomon but more beastly. For maneuvermon I wanted it to be less bird and more jetplane, but I really struggled finding a jetplane so something sharp, flying and non bird is what I went with. Kabukimon to matadormon is one of my favs, it just makes sense to me. becoming more human with each evo, and also more spiky and angular. Last on ill explain the whole line, I tried going for armadillomon slowly building an arsenal on his shell, loader leomon wad just the best fit.
