Primax 984.0 Gamma (Marvel US)
Ironhide was an Autobot soldier under the command of Optimus Prime during the Great War on Cybertron.
In 4 MYA, Optimus Prime assembled a group of Autobots that included Ironhide to take off on the Ark to destroy an incoming asteroid belt that threatened to destroy Cybertron to ensure a safe passage of Cybertron through the Solar System. After the asteroid belt was dealt with, the Decepticons under the command of Megatron attacked the ship. Optimus Prime charted a course to crash the Ark into Earth to take out both themselves and the Decepticons. The Ark crashed into Mount St. Hilary, deactivating all the combatants on the Ark.
In 1984 CE, an eruption reactivated the Ark's computer Aunty who rebuilt all the Transformers, including Ironhide, with new Earth-based alternate modes. The Decepticons fled and the Autobots took roll and subsequently observed the traffic of Earth, assuming that the mechanical creations on Earth were the dominant life form of the planet.

Ironhide was an Autobot soldier under the command of Optimus Prime during the Great War 4 million years ago. He was part of the crew of the Ark that abandoned Cybertron in search for a new source of energy. He served as the ship's gunner. The ship came under attack by the Decepticon warship Nemesis, and Ironhide could not open fire as the gun lost power while the Ark navigated a meteor shower. Ironhide fought on the bridge of the Ark before the ship crashed onto Earth, lodging itself in a volcano and sending the combatants into Stasis Lock.
In 1984 CE, Ironhide was re-activated by his fellow Autobots with a new Earth-based vehicle form. When the Decepticons attacked an oil rig, Ironhide was part of the battle group organized by Jazz and led by Optimus Prime to defend it.
