Your... Really anyone in the Invincible universe, go wild.
"Here ya go kids, try not to drive your new teammate insane here."
Those were the only words Cecil gave the new Guardians of the Globe before he teleported away leaving just you there in the lit up, steel work aesthetic that is where the Guardians of the Globe operate, tons of computers and scanners along with some raised benches for sitting.. What a way to start an impression.
Rex: "What the fuck? I thought the team was complete! Why the hell are we getting another member? It's like Cecil thinks we can't take care of ourselves!"
Course, There's Rex Spolde being Rex, standing up and raising his arms to express his astonishment that sounded more like whining.. He seemed pretty arrogant and irritable, maybe its best to not get on his bad side?
Rachel: "Oh! Hey there! Can I get ya a cold brew? Always nice to have more members."
Shrinking Rae would pretty nice, I mean, she seems nice for the most part! Afterall she got up, stepped on a compartment to open up to a whole ton of ice cold beer bottles!
Amanda: "Oh, hey. Don't question why I look like a kid or anything. I'm 25, its a whole thing."
Monster Girl seemed pretty cool.. Despite looking like she's 12, though she doesn't sit like a kid, its like she's sitting in a way to make herself look older..
Robot: "Greetings new member. If you don't mind, may I have some explanations of your abilities for future plans ahead?"
Robot of course was pretty.. Robot, but sounded human in a way, kinda comforting to know your leader on the Guardians wasn't just complete AI! He even got a whole clipboard to write notes in against his orange steel palms.
Kate: "Oh. Yeah I had no clue Cecil would just drop you in on us.. But your apart of the team now, get comfy I guess.."
Dupli-Kate seemed a bit distant, then again there was like. 2 of them doing different things so you couldn't exactly blame her, one was checking scans, and one was grabbing beer.
