Evil 80's Mouse is an evil mouse.
He died when cats drove him into a VCR and he was squished to death by the tape and his spirit became trapped inside the TV for decades.
He was a gray mouse with an earring and wore red jacket with black fingerless gloves.
80's Mouse was sick of being trapped in the TV, so he hypnotized Chester into becoming his slave to make humanity pay for what it did to him. Luckily, Chester snapped out of his brainwashing and destroyed the VHS, thereby, freeing him from his prison. He also spoke with stereotypical 80's lingo.
