The bulbmin OC would be a rare type of bulborb that's blue and was taken over by a parasitic pikmin, it has control over the bulborb unlike other bulborb leaders, helps lead pikmin and wears a blue bottle cap. since leader bulbmin aren't normally useable I would suppose they would be stronger, I say since adult bulborbs weight 10 pikmin they would be able to carry 10, but since bulbmin leaders are slightly smaller they might not, so I would say either 5, or 10 (because maybe they can carry more than their weight, I doubt oatchi weights 100 pikmin and gets heavier everytime you upgrade his carrying) (update bulbmin leaders weigh 7, so 7 or 5 ig) Also I have two versions of the blue bulbmin
