I have always liked the Seekers...just never really had any til Classics....and now Animated.

I'd have to say that Skywarp has always been a fave.

 

I really like the G1 and G2 Seekers even though their bot modes are pretty awful. I just think their plane modes look so awesome. I have all six of them now, although the two G2 version substituting for their G1 counterparts, but I'll work on those later. I like G2 Ramjet better anyway.

I like the Classics molds too, but have never bitched about the Botcon ones because it's not that big of a deal. None of the other lines that have Seekers have really made me want to try to collect all them.

 

The term Seeker refers to Decepticon jet troopers who all share the same body style. That is, the Decepticons in Generation 1 that looked like Starscream, but in different colors or with minor variations in wing and head shapes, and also the Decepticons in later franchises such as Armada where similar "families" of jets appear.

The word "Seeker" hovered a long time in a strange gray area between official and fan-coined terms. It seems to have originated in extremely obscure official or semi-official writing, but somehow became widely used among fans. In 2002, the term appeared in dialog from the first issue of The War Within from Dreamwave Productions, making it truly official after years of controversy. It has subsequently appeared in many other places such as on toy packaging, books, and in other stories.
