These are Argobolds, an alien species of only seven rogues who steal from food markets. Engage them at your own risk.

From left to right:

Full House, the leader.
Ace, the right-hand man.
George, the ignored voice of reason who avoids conflict because he's squeamish. He's also the least evil.
Cold Streak and Hot Streak, the brawn and the brains (who are carrying Comp, who only speaks in grunts.)

*Not pictured: Wild Card, the traitor who represents greed.*
