Panacea Potion
From Multiversal Omnipedia
The Panacea Potion was a medicine that existed in the time of the Scarlet Centurion, which was capable of curing any disease that could afflict a human of that era. Tom Thumb stole a sample, hoping it could cure cancer, only to discover it merely contained penicillin and a few complex vitamins: the Panacea Potion only acted to boost the already-enhanced immune systems of future humanity.
