"Survival of the Fittest", when played, allows for an attack on Apocalypse to be made on an opponent of Apocalypse's choice, who may defend it.
It's mechanics are similar to that of "Shape Shift", where an attack on an opponent must be made on Apocalypse.
*Note: Original Overpower characters did not include the 4th Stat, Intellect, until the release of the Marvel IQ Expansion.
