Darksteel

Darksteel revels in combat, particularly combat that ends with him standing victorious over a broken Autobot. As it happens, this is most combat involving Darksteel.

Fiction
Following his return to Cybertron, Shockwave succeeded in bringing two new clones, Darksteel and Skylynx, online. The pair were put to work searching for more Predacon remains to continue the cloning experiments. It was while they were searching in what was once the Sea of Rust that they were happened upon by Ultra Magnus and Smokescreen. They attacked the pair, and Darksteel tossed Smokescreen around until the Autobot managed to use his phase shifter to escape. Victorious, the two Predacons returned to Shockwave's lab, only to find Starscream less than happy that they'd revealed themselves to the Autobots.

More searching for fossils ensued, and the pair stuck gold when they discovered a Predacon burial ground. While they were collecting up the bones, Unicron arrived to raise an army of undead Predacons. Skylynx and Darksteel attacked him, only to prove no match for the dark god. They were later found there by Predaking, who swiftly asserted his leadership in combat, and led the pair into battle to assist the Autobots in fighting Unicron's horde of undead Predacons. They were successful in slowing the horde down long enough for Optimus Prime to defeat Unicron, causing the Terrorcons to disintegrate. The trio later tracked down Starscream, intending to exact some revenge.
