Colonel Granite

A colonel in the British army, Percy Granite suffered from megalomaniacal tendencies and xenophobia - so it was an extremely bad situation when he ran into Amy Rose & Tekno, who had just been transported to Earth. He attempted to arrest them on grounds of being aliens and discover how to get to Mobius, reasoning Earth had to attack it to be on the safe side; the girls were able to teleport back to Mobius, but Granite was able to commandeer the technology they used. He used it to develop time-travel technology, intending to conquer the 19th Century with 20th Century weaponry, but was thwarted by Amy & Tekno during their period working for the Eternity Ring.

Granite finally turned to creating a dimensional gateway to Mobius and invading it. On New Year's Eve 1998, he went AWOL with an army regiment and invaded the Emerald Hill Zone, trouncing the Freedom Fighters with superior firepower and planning to sell off the conquered Zones to human industrial developers (and rename Mobius "Planet Percy" after his first name). He was finally defeated by a freak storm that took out his regiment and blew them back through the dimensional gateway to Earth - seemingly, the spirit of nature itself had fought back against Granite and his plans to destroy the ecosystem. He was last seen being arrested for war crimes on the order of the Prime Minister.
