So, I have a Parallel Universe AU with Ace.
In this AU, Ace and the Loonatics are close friends in college before the meteor hit Earth. On that day, everyone was out and about, except for Ace who wasn't feeling too well. Unfortunately for Lexi, Slam, and Duck that day would be their very last. When the meteor hit, it was sudden, and Lexi, Slam, and Duck were immediately killed on impact, not even getting a chance to run. Tech and Rev would die 30 days later due to experimenting with parts of the meteor, contracting an alien disease that quickly ravished their bodies.
Ace was the only one out of the friend group who survived, though the impact broke both of his legs and he lost his left arm.
The impact from the meteor also cracked the Earth all the way through itself, causing the core to start leaking, and causing severe weather almost immediately. Those who survived were immediately evacuated, and are currently quarantined on a large ship. Eventually, the Earth finally split apart, taking the moon with it. With nowhere else to go, Ace (not his real name, he just uses it because he can't remember what his actual name is) bought a beat up ship, repaired it from the inside out, and is now an intergalactic scrapper. He eventually meets Astraeus, a Tammer who Ace mistakes for a literal angel. Through hardships and earning his keep, Astraeus grows super close with Ace, and they eventually start dating. Though the happiness doesn't last long, because Asmodeus, Astraeus's brother, has come looking for Guardian Strike Sword with the intent to plunge the whole universe into darkness so he can rule it with an iron fist.
