Transformation Impossible! The Base Destroyed (変身不能！基地壊滅 Henshin Funō! Kichi Kaimetsu) is the forty-first episode of Choujin Sentai Jetman. It is the conclusion of a two-part story involving the Neo-Jetman and the battle with Meteor BEM.
Tranza shows the others how he released the mini-meteor before the monster was destroyed, and sent it up a robot's exhaust pipe. The bat monster is now in the Jetman complex. The new team shows off at the old's expense and throws the old team out onto the streets. The leader of the new team apologizes. They find the bat-monster and try to fight it, but the general locks them in with it when they try to retreat, while Aya tries to help them. The old team hears their calls for help, as Ako had stolen her bracelet, and rushes in. They are able to briefly beat off the bat monster. The other team recharges the Jetmen, bringing them back up to full strength. The bat-monster is defeated, and things are back to normal.
