Ransack (Ransack (ROTF) - Transformers Wiki) was a contemporary of Jetfire, a fellow Seeker who transformed into a World War biplane. He appeared in the ROTF novelization/comics, where he strafed Jetfire for betraying the Decepticons... and got stomped on by him. He later appeared in the spin-off comic NEFARIOUS. Generally the Seekers seemed to be a take on the HEARTS OF STEEL comic, which featured steampunk Transformers in the 19th century. It was a cool plot angle, and I think it needed more exploration: give Jetfire one more battle, facing his rival Ransack as a kind of old vendetta thing as well as to buying time for the humans to find the Tomb.
