Apocalypse Earth-295 opkit question

[alfred]

I have a question, when you fielded this dice to the Field Zone, you and your oponent roll all your no-apocalypse characters, the energy side dices go to the Reserve pool or the Used Pile.

Many powers allow you to “reroll” a die. When you reroll a die, it stays in the same area it was in unless (a) otherwise specified by the card text for the resulting face, or (b) it’s in a location that the die face cannot be (for example, an energy result in the field). If the die face cannot be in the specified location and its fate is not specified in the card text, move the die to the Reserve Pool.
