Which ninja in K-11 grew the strongest from part 1 to 2?

[Lilvic92]

Sasuke has to be excluded because he improved so much that Team 7 got a really butthurt and accused him of taking drugs.

But since we're exlcuding Sasuke I'd have to say Sakura..she went from being an utterly useless kunoichi who just stood around with a kunai doing nothing, to an ultra strong badass.

 

[Blink89]

It's Sakura, easily. She was a waste of space/panel/time/semen in part 1. She improved significantly and became useful during that first arc in part 2.

 

[Team7monaa]

Sakura.
From A Weak Dependant Pre-Teen to the strongest Kunoichi of her generation.

 

[FemmeFatale]

Sakura when from 0-100 real quick
Although she wasn't the weakest, she had the feats to use chakra enhanced strength and speed

 

[LordRevan]

Sakura.....

 

[Slug Princess Tsunade]

Sakura. Definitely Sakura.

 

[Neji Hyūga2]

Sakura definitely did.

It's hard to say who's after her though, probably Choji then Hinata.

For the most part everyone else were pretty good and still remained good but didn't get as much of a boost compared to the characters I listed above.

 

[Icelerate]

Sakura. She was the weakest and became the strongest.

Fixed.
