Universe Onslaught is by far my favourite Transformer toy ever, but he has one major glaring flaw - the only weapon he has in robot mode is that offensively small wrist weapon. Surely the leader of the Combaticons deserves a much greater weapon! It annoyed me so much that I actually went and customised a weapon for him. The weapon in choice is an Action Man .50 calibre machine gun which I picked up from a car boot sale for 50 pence. The handle was then filed down to fit into his hand, and that was it! It's not the most complicated custom ever, but I'm happy with it.
