Cyber-bat

I came out of Galvatron's mouth!

Added to Galvatron's arsenal when he was upgraded, cyber-bats are small flying devices which attach to their victim's foreheads, causing paralysis. They come out of his mouth.

Fiction

Robots in Disguise cartoon

After Galvatron drained a massive amount of energy from Fortress Maximus, he was confronted by Omega Prime. In response, Galvatron opened his mouth, issuing forth a swarm of cyber-bats. The swarm hung over Metro City as one of their number swooped down, attaching itself to Koji Onishi, mesmerising the boy. Galvatron boasted that he had gained control over Earth's children, forcing the Autobot leader to call a retreat.

Koji was found by his father, who attempted unsuccessfully to find a way to deactivate the cyber-bat. Meanwhile, the retreat was not going well. With the Autobots presumed dead, Galvatron recalled the cyber-bats, taking them back into his body. Galvatron's Revenge

Notes

• In the original Japanese Car Robots episode, the cyber-bats were used to drain mental energy from the children, a fact changed for the dub to downplay Galvatron's state as a sort of "energy vampire".
• They resemble a simplified version of Galvatron's bat form, though in his original Megatron colors.
