Steeljaw has actually appeared quite a bit since the 80's. Granted now as often as Ravage but the name has seen a lot of reuses. Though unlike Ravage who is always a Decepticon panther/jaguar, Steeljaw has been an Autobot lion only four times. One of them being a small cameo in Animated and another being in the Shattered Glass universe which hasn't really been made main stream. Oddly enough the Bayverse actually has two different versions of Steeljaw. The first one being the Wreckers pet from Dark of the Moon, the second being the previously mentioned Lockdown minions which is the first example of Steeljaw appearing as a Decepticon. They're both dogs but the Autobot version is more of a pit bull while the Decepticon versions are wolves. And now there's this guy. I might also add that a more G1 version of Steeljaw is already suppose to have existed in this universe but as I've said multiple times on the forums despite claiming there's an aligned continuity between the games and shows Hasbro seems to be doing nothing to actually align them. FoC Steeljaw is an Autobot lion... though being a toy only character I guess he doesn't really count. On the other had they are a toy company... But that's another reason why Steeljaw is so memorable is because he has actually had a fairly recent G1ish toy release. Even kids who weren't around in the 80's probably have that FoC figure and are confused as to why Blaster's minion is now the Decepticon's leader.
