Heavy Barrel is a Mini-Con from the Cybertron portion of the Unicron Trilogy.

Hi-diddly-ho, minirinos!

Heavy Barrel is a Mini-Con hailing from a long-dead colony world, rescued by the Decepticons and caught up in the events caused by the Unicron Singularity. He is perhaps the cheeriest, most friendly robot in all of existence, which is incredibly unnerving to friend and foe alike. People can at least comprehend the crazed cackling of a hyper-violent sadist in battle. Polite conversation and compliments during barrages? Not so much. It even creeps Buzzsaw out.[1]

Japanese name: Trigger



  • Trigger (Micron Booster, 2005)
    • Booster ID number: 5
Trigger is a redeco of the Mini-Con Crumplezone, transforming into a Cybertronic tank. He can also form a cockpit with under-slung cannon for the Armada Cyclonus mold, though the remolding on Cybertron Buzzsaw makes using him with that version difficult. Available only as part of the fourth Micron Booster assortment in Japan, Trigger came in a "blind-packed" box that prevented the buyer from knowing the contents of the box until it was opened.


  • The packaging for the Micron Booster assortment Trigger was available in does not give any of the Mini-Cons a faction affiliation, so for a time, it was unknown who the Mini-Con associated with. It wasn't until he received a bio (and new name) through the Fun Publications Official Transformers Collectors' Club that "Heavy Barrel" was officially pegged as a Decepticon-allied Mini-Con and partner to Buzzsaw.
