Whiplash

Ivan Vanko / Whiplash
A disgruntled physicist and Bratva member, Vanko serves as the main antagonist of the film, forging a suit (a harness containing his own arc reactor, which powers two electrified whips) to pursue a vendetta against the Stark family. He is the son of Anton Vanko,who in the film collaborated with Howard Stark on the original arc reactor technology years ago. Howard Stark, however, took sole credit for inventing the arc reactor — which powers Tony Stark's factory, Iron Man suit and chest-mounted electromagnet — and had Anton discredited and deported back to the Soviet Union to live in squalor. The two disagreed on how to apply the new technology: Anton sought to use the reactor for military and industrial purposes to make money while Howard saw it primarily as a humanitarian invention. Disguising himself as fire marshal B. Turgenev (a reference to the second Crimson Dynamo), Ivan attacks Tony Stark with his Whiplash "armor" at the Circuit de Monaco. Vanko dons a suit of gray armor with features highly reminiscent of the various Crimson Dynamo suits, as well as upgraded whips from the Whiplash suit.
