Swapper

Swapper (voiced by Frank Welker) is Experiment 355 of Dr. Jumba's Experiments.

Primary Function
Swapper can emit a green ray from each head's eyes once each head is pointed at one of two individuals, but one time he hit four beings at once, but the complete limit of beams is unknown. The ray will swap the minds and voices of the targets, as well as vice versa, and the only means of returning to normal is through Swapper choosing to do so. Swapper has some of the basic experiment attributes, including scaling walls and rolling into a wheel-like shape, rather than the basic ball-like.

Weakness
Swapper is terrified of Pleakley 's cuisine, as he immediately gave in to obeying once threatened with only being fed with it.
