Twitchy:

Twitchy was born to an indigenous tribe of reptiles which was attacked by a more technologically advanced organization of mammals, leaving Twitchy orphaned from only a few weeks old.

After the attack Twitchy was sent as a factory hand in an illegal weapons manufacturing plant, initially jumping and dropping what he was carrying at every instance of loud bangs coming from the machines and weapons testing, he grew a curious fondness for the shapes, sizes and smells from the weapons he wasn't permitted to touch.  He began watching the manufacturing line, stealing small enough parts as to not get caught as he began crafting his own weapon out of; a Grenade Launcher, multiple Assault rifles, a high caliber sniper rifle, a shotgun and a couple of untested laser weaponry, to create his *Boom* (never being taught how to speak he refers to it by make a *Boom* sound that it makes).

After finishing his very own weapon he began testing it out.  The weapon combination left nothing but destruction in its wake, rendering the weapons factory to ruins, as being small and utilizing the weapons spinning to travel quickly he was only caught when he ran out of ammo.  Coming face to face with the owner of the factor GOLD BOSS who instead of punishing Twitchy, hired him as a weapon designer to sell to the highest bidder, Twitchy accepted and started upgrading his *Boom* to hold more ammo eventually constructing the FunFunFUN Blaster Mark 2300.67 scratch which is seen in the trailer.
