Prime Forms

Prime Forms?
A Prime Form is the ultimate and last form of a character in the DC X DBZ. They are the most powerful forms of the character. When a player unleases a Prime Form, a movie sequence occurs and everyone can see it. Prime Forms also bring special qualities to the player. Unlike other forms, Prime Forms stay active after players are damaged. And they stay active from when it is released to when the player dies. Because Prime Forms are so powerful, they also have special requirements that need to be filled in order to use them. Requirements may vary. But most will most likely be unlocked when the player has 50% health or less.

Only Superman has a Prime Form so far. But it is predicted that all characters will eventually get one.
