Thunder Bunny is a sorta Marvel Bunny who seems to have been named after the Thunder Agents*. His comics were originally obscure independent efforts, but the character was later picked up by the Archie comics people. This particular story was published in 1984, with words and pictures by Martin Greim and Brian Buniak.

*They had originally intended to call Captain Marvel "Captain Thunder". If they had, Hoppy the Marvel Bunny presumably would have been "Hoppy the Thunder Bunny" or something similar.
