i've got two question
chopper has 7 transformation right and says he needs the rumble ball only for one transformation (propably the giant one)
but even if i take that into acount i only count 6 forms on that page or did i miss something?

and didnt chopper had 7 transformations without the giant one already so shouldnt he be abel to have 8 now 😕

* 2.1 Normal Transformations
o 2.1.1 Walk Point
o 2.1.2 Brain Point
o 2.1.3 Heavy Point
* 2.2 Rumble Ball Transformations
o 2.2.1 Jumping Point
o 2.2.2 Guard Point
o 2.2.3 Arm Point
o 2.2.4 Horn Point
o 2.2.5 Unnamed Monster Point
* 2.3 After Time Skip
o 2.3.1 Kung Fu Point

i think the monster point doesnt really count? as its a side effect of the rumble ball which requires chopper to take 2 balls instead of 1...(heehee)
but like you said, i think oda missed something or misprint? (ps i dont even remember kung fu point until i checked it up) does anyone remember when he used kung fu point?

side note have we seen what heavy point looks like after time skip? i'm looking at his picture now and i noticed his fur around his upper body before time skip. Now that chopper has more fur when hes in walking point do you think the dur will cover his entire upper body when he turns to heavy point?

I think his default transformations aren't even counted as part of them. you never needed the rumble ball for them in the first point. so we have currently have only 5 transformations (minus monster point)

monster point took 3 rumble balls, not 2.

acctually

it would seem that he needs the rumble ball for guard point

He used it in ch. 614 against Fishmen trying to arrest the strawhats.

If anything, I'd think he'd have less fur considering that Heavy Point is his true "human" form. Maybe he'll actually look like a regular person instead of his typical gorilla-like self.

wow your right he needed rumble ball for guard point
but that means that he still has 2 transformations left
cuz doesnt he say something like he only need rumble ball for 1 transformation
but can switch between the other 6 as he likes...

this is confusing isn't it...?

anybody read 645 yet? Awesome monster point :D no wonder he kept calling himself a monster.
