Conehead

Conehead is a tongue-in-cheek fan term for the Seekers that were released in 1985—Thrust, Dirge and Ramjet. Though the toys were virtually identical to the original Seekers, their animation models were given a distinctive transformation that left the jet nosecone pointing up, hence the nickname. Another change brought to the Coneheads is that their wings don't flip up to appear as part of the upper body, and instead seem to be part of their legs (although Thrust's wings did flip up, they remained part of his legs). The animation models for the Conehead Seekers were designed by Floro Dery, whereas the season one Seekers were done primarily by Japanese designer Shōhei Kohara. The name "Conehead" is taken from an early "Saturday Night Live" sketch about a pointy-headed family from ~~France~~ outer space.

A simple way to remember which of the core six G1 Seekers are Coneheads, is that the names of the Coneheads are real words, as opposed to made-up words such as "Starscream".
