First on-page demonstration that Chopper’s Devil Fruit grants multiple discrete physical forms, not a single binary transformation. The chapter shows two — small bipedal (his default carriage) and the towering humanoid (rage-triggered) — but their relationship is not yet explained. Forward-canon: the Rumble Ball will enable six discrete Points (Walk, Brain, Heavy, Jumping, Arm, Horn) plus Monster Point. The Ch. 140 humanoid is the Heavy Point form before it is named — first instance of the Six Transformations system.
