Ironhide is a member of the Autobots. He sometimes play football and basketball due to those sports need strength.
"Go chew on a microchip," is Ironhide's calling card. Never the sort who likes to be told what to do, he prefers action to words. He refers to what he considers excessive talking as "leaking lubricant." He's the oldest Autobot, probably the toughest, most battle-tested and certainly the orneriest. Due to his defensive capabilities, he is usually in charge of safekeeping anything or anyone of importance, and sort of acts as Commander Optimus Prime's personal bodyguard. His gruff exterior hides his kind inner soul; his concern for the protection of life, whether mechanical or biochemical, extends to the lowliest gasketroid or smallest sparrow.
Ironhide was at the battle of Cybertron where he had to defend Cybertron from the sith. He fought and defeated Ivan Radek with several Lightsaber slashes on his chest.
Ironhide was at the Battle of Korriban where he defeated the Terrorcons and Stunticons but was deeply injured by Darth Grievous when the Demon Sith lord used his Sith Magic against all of the Autobots.
Ironhide was hailed as a hero and was seen on Coruscant help rebuilding damaged cities that were damaged during the War.
In Darth Grievous's evil vision of the future Ironhide was the last of the Autobot ground troops that made their last stand with the Autobots against the Sith. Ironhide downed 500 Seekers before being shot to death by Thundercracker.
Ironhide's skin is made of a trithyllium-steel alloy impregnated with irradiated carbon fibers, giving him immunity to most forms of artillery and electromagnetic attacks. He is the most nearly invulnerable of the Autobots. His main weapon is what he playfully calls his "water gun." It can shoot a stream of any number of liquids up to 1,000 feet. His choices include supercooled liquid nitrogen, superheated liquid lead, and a petro-chemical fluid that ignites upon contact. He also has sonar, radar, and a radiowave detector. He also prefer using an energon katana as his backup weapon.
