I'm not sure what exactly you are asking, so I'll give a couple answers.
If you're asking why I don't think ABA will return soon in GG, no real reason other than that she isn't as popular as several other characters, so she's probably a lower priority unless they decide to ignore that.
If you're asking who ABA is, she was added to the series in Isuka so she's only been in three games. She starts off slow and weak, but she has a couple ways to change into a berserker mode that is fast and strong for a limited time, so she has to balance switching between the two forms throughout the match. It's a pretty cool playstyle.
Thanks! I actually do know ABA, but I thought she was more popular than that. I agree she could be a good template for Kale, but IIRC it might be an even better fit for Launch... If they don't forget she exists.
