Ironhide is one of the oldest and toughest Autobots, and has been on Optimus Prime's team for a long time. "They don't make them like they used to" is an apt description of Ironhide—he's yesterday's model, but he's built to last.
Gruff and ornery, he prefers actions to words, and dislikes talk for talk's sake. (He wouldn't enjoy being paired up with Bluestreak.) But though he may be rough around the edges, he's still optimistic and upbeat. The upside to being through more than your share of trouble means trouble ain't so big a scare anymore.
