Fiction

IDW Generation 1 continuity

When Whirl quit the Aerial Corps and became a professional watchmaker, he caught the attention of some criminals who demanded a cut in his profits. When he refused, they sent their enforcers, the Heavies ("both of them"), to destroy his business, leaving him without a job. Interiors

The Heavies accompanied Kroma and Macabre to the location where Senator Shockwave was being kept to kidnap him. Orion Pax killed both Heavies by driving through one and tossing a bomb at the other. An Intimate Beheading

Notes

• Given that one Heavy is called Anvil, there's a fair chance that the other one's name is Hammer.
