If you'll recall, in More Than Meets The Eye it was Hound that was Spike's bestest buddy. It even made a weird kind of sense, since Hound connotes a dog. Yet, in the first episode of the regular season, all that switched to Bumblebee for some reason. It was Bumblebee that was sent out to locate the Decepticons, not Hound. Wtf? Isn't that Hound's specialty? Anyway, if they had continued the relationship from MTMTE throughout the series, Hound would still be alive in The Movie, he would've been featured in the current film, and likewise he would probably be in Animated. He might have had a Pretender and an Action Master figure as well. The most mind boggling thing is, Hound cost about 4x more than Bumblebee in retail. Wouldn't you rather promote the more expensive toy than the cheaper one?
