Like Weiss, Ruby also have an alt color in BlazBlue Cross Tag Battle. However, there's one major problem from what I've read and watched on Youtube. The core game itself only has 20 characters available with Ruby and Weiss the only RWBY characters available. Blake herself and presumably Yang are DLC characters along with a few other missing characters from BlazBlue itself, Persona, and Under Night In-Birth. Thankfully from a recent article I've just looked up just now, both Blake & Yang are free. But that's not exactly saying much as the rest of the DLC characters are paid DLC and if only Team RWBY themselves are going to be the inclusion of the game as a whole, that probably means that no Team JNPR, CFVY, Sun Wukong, Neptune, Qrow, or even Cinder's Faction. In all fairness, BlazBlue are most likely the focus since their name is on the game. But by that same token; depending on the characters and which franchises they're from, if they're all not from RWBY, meaning that only all 4 of Team RWBY are playble. I think we can do better Arc System Works. Speaking of Blake and Yang, I'll work on them too in their Volumes 4 & 5 look.
