Keeping with his ant mentality, Inferno has absolutely no regard for his own personal safety whatsoever. He is fanatically loyal to Megatron, and as such will use his heavy firepower and incredible strength full-on and take any task given of him, no matter how suicidal. And he'll do it laughing maniacally the entire time, for the glory of the colony.
An alternate-universe iteration of Inferno was caught up in the Universe war and joined the Autobots. No, really. Another one was rebuilt into a Vehicon, then also ended up in that war.
