-   Billy had been working on a Zeo Megazord / Red Battlezord interface to form the Zeo Megabattlezord; the interface relied solely on the Battlezord's control system, using a neural impulse reader to tie directly into Tommy's brain, and it wouldn't work unless Tommy's thoughts and emotions were clear.
-   To form the Zeo Megabattlezord, the Zeo Megazord and Red Battlezord would stand back-to-back; the Red Battlezord's legs would grow longer, and its arms would rotate back to become the Megabattlezord's shoulder cannons; finally, the Battlezord's head would become the Megabattlezord's helmet, sliding down over the Zeo Megazord's head.
-   Twice, the Zeo Megazord and Red Battlezord tried to merge but were shocked by orange electricity, as Tommy was unable to clear his thoughts.
-   Billy began work on a bypass device for the Zeo Megabattlezord, but he couldn't get it to work.
