A Predacon attack on the Maximal base leaves it malfunctioning, necessitating the Maximals to remain in beast mode until it is repaired. However, the longer they stay in beast mode, the more their animal sides start to take control.
A Predacon raid takes the rectifier coil for the Maximal ship, the device which shields it from energon. Without energon shielding, the Maximals are forced to remain in beast mode. After days in beast mode, the Maximals slowly begin to give in to their animal personas and make themselves easy targets for a Predacon assault.—Anonymous
