Seems everyone and their mum has a different idea for how to customize a Siege Caliburst, and I'm no different. Here's my take on the three blue-grey-gun-men Blowpipe and Aimless are the official figures with some added paint for flavour. Caliburst, however is a Firedrive with much more paint than his compatriots. Together they can even combine via the 3mm pegs intended to enable the robot modes to wield the gun barrels as weapons. It's also worth noting that I don't have a TR Triggerhappy and am also missing one of Caliburst's blast effects.
