Alpha Alpaca: (Somewhat nervously) Well, you see, I really didn't have a choice. You're kind of automatically conscripted to the Alpaca Apex back on Argon as soon as you can walk and contra your powers. Doubly so for me considering I was part of a super soldier project when I was a baby, led to me aging slightly faster than a normal Argonian as well. I decided to become a 'superhero' in the more traditional sense when I was called to Earth to investigate a distress call. Turns out it was just a bunch of criminals setting a trap for me and stranding me there. I decided to gel this planet that always seems to keep getting itself into trouble so the can stop spending so much on meaningless conflicts and disasters and focus on getting their space program up to galactic standard. Namely so I can finally get back home to Argon.
As for where I got my powers? Well, they come naturally to Argonians, though some like my friend Boreas Starwind and his group, the Four Winds, are injected with nanites to grant them elemental powers as well. My suit also gives me a few neat tricks as well like minor weather control and the ability to negate my own personal gravity.
My greatest archenemy would definitely have to be Dr. William Goatmilk, at least until he died in a lab accident I may or may not have had a hoof in. Now, it's his daughter Dr. Bille Goatmilk. She's basically that one girl in high-school who keeps spouting darkly comedic non-sequiturs about waffles and tacos while pretending to be some great evil with or something except she's an accomplished mad scientist who builds doomsday weapons each Tuesday. She's kind of a pain. There are also quite a few others in my rogue's gallery as well, including my buddy Boreas Starwind when it's a bad day for him. (He motions to the large and muscular white Alpaca in the silver armor with an appropriately icy expression on his face.)
