Chuffer is dumb. And now he's dead. Serves him right.
Note:Chuffer is never called by name in the story in which he appears. He was given two different names later in response to questions asked in letters columns; Grimlock dubbed him Chuffer, while several issues later Dreadwind called him Steamer. Dreadwind was called on this by a human reader, and he admitted that Grimlock probably knew his Autobots better.
