A quick background on Ruler: He's a human/mutant from Earth, but was abducted by the Haessa when he was young and turned into an emotionless weapon. And by emotionless I mean he biologically lacks emotions. Ruler slew his masters and took over Haessa. He then led them to Fomalhaut - the planet where the race that invaded Earth back in 2008 lived - and co-existed with the natives. With Fomalhaut looking for a new planet, Ruler recommended Earth, making him directly responsible for the invasion.

So what am I looking for? I had a thought that Haessa may have made a previous weapon before Ruler, but that weapon was deemed as a failure because of the emotions he/she/they possessed. Emotions are considered abnormal in Haessa society, though they do have basic ones like being content, being sad, etc; they practice the precision of language (eg. The word for "love" is considered obselete because it's too vague. Instead, they say things like, "I am happy for your achievements" or "I enjoy your presence." If you've read The Giver by Lois Lowry, that's exactly what I mean. For more info on Haessa, click here.) So they might have tried to terminate your character either by execution or abandoning them in space.

But the character lives! Either by escaping or surviving the execution. It's up to you then what that character would be up to after that. I can't really give you a conrete plan for it since it would depend on the character's personality, which would be up to you as well. If your character somehow turned out to be a pleasant person, they might align with Earth to protect it from Haessa and Fomalhaut. If they're vengeful, they might have gone after Haessa and had encounters with Ruler before - and might have somehow followed Ruler to Earth. Your character might have even become leader of a race, much like how Ruler became so PARALLELISM!

So we can have Ruler/Character either be enemies or allies. If they're allies, it would be neat if one of them (probably your char) decides to align with Earth in the end, making for some epic fight between two superpowered psychics. If enemies from the start, we get an epic fight between two superpowered psychics still.

If there's anything I'm looking for, it's a less cliched nemesis relationship. They're not linked by hatred, but by understanding because they do have a shared background by being Haessa's weapon. Ruler may envy your character for still possessing emotions. For that, he may actually value your character's views more than his own. In turn, your character pities Ruler, but admires the way he has fought to regain his freedom and humanity. Something like that! If they're enemies, it's not impossible that they become friends in the end. So there's all sort of possibilities!

For you character's race, I would recommend making them a homo lunaris (see tab IV) since their females are natural psychics. If you want to play a guy though, you can make them a tranvestite, or simply a unique case. As for FC (if you're not set on playing a female), we would have cute fanart/gif together if you FC Soldier Blue from Toward The Terra. Tony Asuka is also an alternative! Naturally, I don't really mind in the end xD. Plot > Everything else.
