Sunstorm. Originally just a generic amber and white coloured Decepticon jet who featured for like a second in "More Than Meets The Eye Part 1" alongside equally generic looking blue and white and purple and white Jets (as can be seen
here) - blink and you'd miss him. Then in 2003 e-Hobby released the G1 Sunstorm toy - so suddenly this generic and forgettable generic Jet had a name and persona as written by Ichikawa Hirofumi. Since then he's appeared in the
Dreamwave comics,
Universe,
Cybertron, and of course the sycophantic
Animated Starscream clone. ;)
And if TakaraTOMY ever made a
Masterpiece Sunstorm, I'm sure he'd sell like
hot cakes!
