Rumble Ball

After two years of research and training within the Torino Kingdom, Chopper had mastered his physiology enough to access all four of his "standard" Rumble Ball forms (as well as new ones, e.g. Kung Fu Point) without actually taking the drug. As such, his only remaining use for it in the New World was, and still is, his "Monster Point", which he could now utilize for three minutes without losing any conscious thought, and he only needed to take one Rumble Ball to access it. Although, even with his new level of control, "Monster Point" did still leave him drained of energy and unable to move after he changed back.

The latest version of the Rumble Ball (developed with help from Caesar Clown) strengthens Chopper's abilities even further, allowing him to stay in his "Monster Point" transformation for thirty minutes'. However, entering Monster Point still risks a severe disadvantage, as its expiration will leave Chopper in a shrunken version of Brain Point, largely powerless (and, for unknown reasons, prone to antiquated speech). Exactly how long this form lasts before Chopper turns back is unknown. It is also unknown how long Chopper has to wait before he can safely take another Rumble Ball.
