Okay, on the pages for Ultraman Zero and the Ultimate Aegis, it says that the dimensional travel ability drains the power of the Ultimate Aegis after it's used, forcing Zero to store it so it can recharge.

But that blatantly contradicts this scene from Ultraman Ginga S Movie Showdown! The 10 Ultra Warriors!





Not only was Zero able to keep fighting in his Ultimate Zero form after crossing dimensions, but he was even able to use the Final Ultimate Zero! I think it's just the Final Ultimate Zero that drains the power from the Ultimate Aegis, and he has another reason for getting rid of it after crossing dimenisions.
