Yeah you don't wanna treat someone like a pet so something like space cadets would be bad lol, IMO anyway, maybe take inspiration from nerfighter's, team gamertag.... People like to join a club, I say buddy personally but that's me making fun of myself for something I said a while ago and it's easier to call people something when you say hi, I kinda like it actually i think it's friendly anyway. Stay clear of spacers lol. But if I had to pick for you knowing nothing but you're a gaming channel I would go with.... Astrobro's
