Viking Spawn
Super Freak
Not even Ironhide?
He was cool too. But he didn't get enough screen time and when he was killed off, it was like no one really cared.
Again, poor writing and development. When Coulson died in the Avengers, there was a turning point with the other characters and the fans (like myself) were in an uproar. He was a secondary character that was very likeable which is how Ironhide should have been.
