A megaman crossover with my favorite character: Dr. Albert Wily.
After the events of Megaman Classic Dr. Wily gathers the Robot Masters and decides he's fed up with the world, choosing to start again somewhere else with his and his rival Dr. Light's robotic creations. He uses the teleporter to reach Equestria. When his inventions have proven to be useful to ponykind Celestia takes him under her wing, watching his every movement. She doesn't trust the man from another world. Is she just being judgemental because she can't stand his ego and his twisted philosophy, or are he and his 'sons' really a threat to her country?
My own interpretation of Wily and the Robot Masters, heavily influenced by his portrayal by the band 'The Megas/Entertainment Systems' and in the manga 'Megaman Megamix/Gigamix', which is what I got the cover image from. Caution, this is a darker Wily than in the games.
