I can agree to that:
Vaaran and the Crew (Updated):
Vaaran and Luji would get along, but Vaaran would be constantly confused by Luji's physiology. He'd likely end up getting into foot races that Luji would always be faster at, but Vaaran would run farther. He'd also probably toss the most random shit at Luji for him to eat, and then be amazed he can actually eat it, unless he regurgitates it. And then he'd be grossed out but still amazed. They would teach each other a lot about their respective cultures. They would likely develop a close relationship and help each other both in battle and on the ship, bonding through their semi-childish antics.
Vaaran and Kadan I could see practicing melee together. They might not be the best of friends, but they'd get along just well.
Laura he'd probably piss off a lot just joking around with her, but they'd usually end up smiling by the end of it. Likely the two would have a minor prank war going on. Hiding random things in each other's gear, messing with the unimportant presets on their mech controls (changing of the music, causing the computer to recognize them by a different title, little stuff that would be annoying and funny, but not interfere in a situation that requires absolute control of the the mech, such as combat or recon). They'd get on each other's nerves, but be friends when it's all said and done.
He'd tolerate Hara at best, seeming comfortable around him but he'd never trust him all the way. His people are too manipulative. He'd probably start calling him Drow as a derogatory term, since his appearance is similar to that of Dark Elves or Drow from old Terran fictional literature.
He would not get along with Kin. Kin wouldn't get along with anybody, and it becomes even less likely considering Vaaran's happy-go-lucky jokester attitude. They'd work together efficiently, but not much of a close bond would form.
Ancyn has his respect. A tough go-getter with a positive outlook, a harsh reputation, and a heart for a thrill and a challenge, Vaaran considers her an equal worthy of his loyalty.
Again, I'll add Leon once he is completed and approved.
