The rookie of Team Prime, Ironhide has a major case of hero-worship towards both Optimus Prime and Hot Shot. He joins the team in the very first episode, in the hopes of earning a Combination Spark.
Optimus Prime paired Ironhide with Kicker, in the hopes that the two would help to keep one another under control. Neither was very happy with the partnership at first, but eventually they became good friends.
Ironhide did manage to earn a Combination Spark after several battles, making him able to Powerlink with Jetfire and later, Cliffjumper. Along with several other characters, Ironhide was reformatted into a new paint job to fight Unicron.

- Japanese ID number: SC-04
Ironhide transforms into a dorky blue sports utility vehicle with a rather oversized red speaker/gun turret/high beam lights/thingamajig setup mounted on top. In robot mode he is able to combine with most Autobot Deluxe and Mega sizeclass toys.
The japanese release, named Roadbuster, had some minor deco and colour differences, most signifcantly being the tan plastic parts being replace by grey, even though they remained tan in the Energon cartoon. The major functional difference between the two toys is that the japanese version does not have electronics, while the US release does.
Ironhide became a major shelfwarmer during the Energon toyline's run, with some areas still having unsold Ironhides well into 2005.
