Brawl Spires would be super skittish, but have like a secret sadistic side that emerges when you make them mad, with little regard for their own health. "NO REPAIRS, NO COWARDS!"
Sniper Spires would be like a super duper chilled out, serious person that is dedicated to the craft of H.Flak kills from 2km.
Mobulas would be sort of matronly and pillow-y soft personality, belying it's inherent capability, at least until you threaten it or it's allies, where it then bombards you with explosives verbal abuse and flaming cannonballs wooden spoons.
Either that, or a shy person with tons of potential.
Except Daniel's Mobula, it'd have a super inflated ego.
