What was the name of that girl that has the dark power of turning herself into a man? She has to be my favorite Bey-"girl".

I dont know, I only seen the first 3 seasons, and cant remember It there,

But That sure is an awesome Power.

Oh I actually mixed my shows. Mixed Beyblade with Bakugan (which both I have only seen one season) but yeah, I actually don't remember many girls in Beyblade except that pink haired girl who I don't even remember the name.

There are 2 pink haired girls in the first 3 seasons, and you probably mean Meraya(Mariah)
The hottest of them in my rating.

And you mean Alice I think in Bakugan, she was sort of turning into maskerade or how he was caled.
I dont like her at all.

Yep, both are correct, and true Alice as a character is very poor but as a conflicted villain he/she is kinda cool, I don't know... I kinda like the concept.

I Heart, Meraya.

I do so too.
But I also like some more of them
