Axl Low, an English man of the 19th century.
Time travel is not new to him, in fact it's common. Too common. He's spent some time in years thousands away from his own. There, he found that fights were the normal thing to do. He's slipped once more, but find himself in a very different situation. He's introduced to the ponies of Ponyville, and sees, very clearly, that most of the days here are peaceful days.
With this peace, he's finally able to relax. How will he get home? He doesn't know, but he's been working on it for thousands of years. Maybe the secret lies with the unicorns?

My first story of a Crossover with Guilty Gear. The first of three. keep an eye out for "Peace Gear - Chipp" and "Peace Gear - Faust".
