Beast Wars Neo
Stampy is a Maximal with "Mighty Ears" to allow him to hardly miss any distant sounds. He transforms into a white rabbit, and can also become a Targetmaster-like firearm for his fellow Maximals.
Stampy had a biography printed in the Beast Wars Sourcebook by IDW Publishing. He also appears in Beast Wars: The Ascending as part of the Pack, a black ops unit of Maximals led by Lio Convoy. Stampy and his comrades go looking for their missing teammate Razorbeast in Earth's past, and eventually find him embroiled in a time-displaced extension of the Beast Wars triggered by Magmatron.
Stampy later returns to Cybertron to help battle Shokaract, and during the encounter with Big Convoy's forces it is learned that the majority of Maximals-or at least those familiar with him-believed that he had been killed in action, when in reality he had been recruited to the Pack.
Andromeda conducted an interview with Stampy's mother Kitte Shūshū, who revealed that-at least in her reality-Maximals have organic elements integrated into their being; Stampy was thus born through biological reproduction as the child of Kitte and Z Grill, who named him after their mutual love of stamp-collecting.

- A new mold that has not yet been reused. He was sold by himself, as well as in a two-pack with the Predacon Sling, called "The Showdown in the Grassland."
The Stampy in the Animated line is a homage to Beast Wars Neo Stampy, although he is depicted as an Autobot. His tech spec appeared on a lithograph sold at Botcon 2011.
Stampy came online right after the great war.
