Very few people within Transformers gets to be remembered long after their involvement in a particular series, and when you think of Animated, there was really just one person behind it - lead character designer, Derrick J Wyatt, and according to some fansites this morning, he died suddenly earlier this month (I couldn't see what was the cause).
Derrick was also one of those people who was a fan himself, and involved himself with the fandom (online, publications, and conventions), making him one of the more invested people behind a series, to the extent that Animated was one of three or four enduring Transformers series (lived on beyond its release).

As someone who has been to several conventions he was at (he would attend BotCon as a fan if he wasn't an official guest), he was a really nice, friendly guy, who loved his work as much as we loved him doing it.
