Count van Rani, AKA the Iron Klaw, is the ruler of the Eastern European nation of Kalistan. Despite his rather menacing manner of dress, sinister nickname, choice to live in a giant castle, strong financial ties to shady corporations, army of brainwashed Transformers, and membership in a cabal of supervillains, we're sure he's a perfectly nice guy.
Count van Rani was the number two stockholder in the I.R.O.N. corporation and, as such, was responsible for choosing an interim CEO after Garrison Kreiger disappeared. His choice was Tomax Paoli, former head of Cobra.
Having lent out his Iron Castle for use as a base for their villainous cabal, Iron Klaw met with his ally Baron Ironblood as he returned from sending Tomax on a mission to retrieve the Project: Ice Man protocols. Noticing Ironblood's distaste for Paoli and guessing that the two of them must have some history, van Rani then showed off his brainwashed Predacons to the baron before he was interrupted by Kreiger messaging him about Tomax's unexpected request for extraction. Later, after the Revolutionaries and Snake Eyes' infiltration of and subsequent escape from the castle, van Rani was quite displeased by the ease with which the heroes broke into their operation.
After Doctor X informed them that the teleporter was ready to transport Kreiger and Ironblood to the Project: Ice Man facility in Brasnya, Iron Klaw commented that he was happy to have his castle to himself again.
Iron Klaw was among the villains contacted by Baron Karza with an offer to begin working for him after he completed his conquest of Earth.
- Iron Klaw originates as the antagonist for the... *ahem* extremely 90s G.I. Joe reboot G.I. Joe Extreme. There, von Rani (as opposed to van Rani as he is in IDW) presented himself as the benevolent ruler of Kalistan when in reality he was Iron Klaw, the vicious leader of S.K.A.R.: Soldiers of Khaos, Anarchy, and Ruin. Whether IDW van Rani's villainy is a matter of public record or not is unknown, though Action Man and Mayday's reaction to hearing his name and knowledge of his pseudonym in "The Secret of the Mummy's Tomb" may point towards the former.
