Teamwork

Zig

• The leader. He makes the plans. He keeps the team in shape. He's the brain and everyone else is the body.
• He also gets called "aniki" by Gorrik in the Japanese release, which I think is awesome (I wish they kept something similar to that in the English one). 
• He's not the type to just laze around, though. If he wants in on the action, he'll join. 
• He also probably has the best relationship with Dyrus out of the three of them. (and by "the best", I mean that Dyrus doesn't think he's as stupid as the others)

Beht

• The guys would make him responsible for all the stuff that requires book-smartedness (leave the logic to Zig, though)
• Weird mechanism? Beht checks it out. Old, rusty device? Leave it to Beht.
• Although he can't keep a secret any better than Gorrik, he'd try to put his charisma to use in *attempts* to do some social distractions and acrobatics. Like, be some homme fatale or a even a femme fatale since (at least, by some players) he's mistaken for a woman because of his stance/posture and the vagueness of his identity
• He's probably the most fearless of the three (not brave, but he abnormally lacks a sense of danger). He'll swagger past a "CERTAIN DEATH AHEAD" sign and try to prove you that things aren't all that bad. See?

Gorrik

• Clearly, he's supposed to be the muscle of the group. He'll push boulders for you. Dig holes for you. 
• Although he may seem like the "good" one of the three, he probably wouldn't skip a second if he was ordered to punch the lights out of someone or something that gets in their way
• He's also what the guys use as "bait", who the guys put on the front lines
• Also used as the team's official meat shield 😔
