Iron Ring

The Iron Ring is an organization from the IDW portion of the Generation 1 continuity family.

When Joe Colton, thought dead, reemerged as the fearsome Baron Ironblood, he became the founder and overseer of the villainous Iron Ring to counter Optimus Prime's annexation of Earth into the Council of Worlds. Forced to go outside the law and betray his ideals in the name of Earth's sovereignty, Colton assembled a motley group of ne'er do wells from a variety of sources: ex-Cobra operatives, supervillains, mercenaries, mad scientists, and even a handful of aliens.

Drawing on Garrison Kreiger's I.R.O.N. assets and based out of Count "Iron Klaw" van Rani's Iron Castle, they stand poised to take down Cybertron itself — and may very well succeed.

They're very on-point with their theming game.
