SSJ Goku vs Full Power Frieza (Destroyed Namek): This remastered iconic scene from Dragon Ball Z is the tutorial for the Dragon Ball story line. It is also a vision Ruby Rose receives in her dream, right before worlds collide.

Those are just some of the many battles in all the Story Modes! Oh, and one more thing: Some worlds, like RWBY and Blazblue, will be in English, while others, like Dragon Ball and Naruto, will be in Japanese. Don't worry, the characters can still understand each other! You can give your OC any voice, even existing ones! Since Goku is voiced by his Japanese Actor, Ruku will be voiced by his English Actor! Pus, I think it would be just plain cool to see the characters Lindsay Jones/Saori Hayami and Sean Schemmel/Masako Nozawa fight each other, using Crescent Rose against Super Saiyan, and Silver-Eyed Warrior against Mastered Ultra Instinct! Speaking of which, I even have my own Rivalries listed! And here they are!
