Ironhide
The character designers for the cartoon redesigned Ironhide's body, which is now the best-known of all his appearances. Despite being known for being part of the Autobot security detail and Optimus Prime's bodyguard, Ironhide was most often seen in the capacity of a warrior, often fighting in battle without Optimus Prime, or a specific worksite/person/cargo to protect. He was also used as an officer, leading a team of Autobots just as would Optimus's advisors, Prowl and Jazz. Ironhide seemed to develop a bond with the Autobots' human allies, engaging with them on a friendly basis as much as protecting them. Ironhide was good friends with the female Autobot Chromia.
