He was briefly seen fighting alongside the Transformers of two eras against Galvatron during the Time Wars.
Ironhide would go on to fight against Ratbat's forces on the moon shortly before the crews of the Ark and the Steelhaven joined under one banner. He vanished partway through the escapade, around the time Scourge dropped a crate on him, presumably injured. It went poorly - so poorly the beaten and humiliated Ironhide was desperate enough to salvage Megatron & Soundwave to temporarily take command of the Autobots. When the time-travelling Galvatron arrived in 1986 and Optimus Prime & Prowl were both lost in Limbo, Ironhide was one of the Autobots who battled the Decepticon.

Ironhide was one of Cybertron's great warriors, and chosen to join the Ark mission to save Cybertron from an asteroid belt - a mission that saw him stranded on Earth for four million years. Note: Ironhide was originally drawn resembling his toy, and abruptly turned into his more familiar animated form later on.
