Mad-Dog (Robert "Buzz" Baxter) is a fictional character in the Marvel Comics Universe.

The character's first appearance is in Miss America Comics #2 (1944). His first appearance as Buzz Baxter in modern comics was in Amazing Adventures #13 (Jul 1972), and his first appearance as Mad-Dog was in Defenders vol. 1 #125.

Robert "Buzz" Baxter was born in Centerville, California. He and Patsy Walker were high school sweethearts, and got married shortly after graduation. After high school, he joined the USAF, serving in the Viet Nam conflict, eventually earning the rank of colonel. He later became the security consultant to the Brand Corporation. He began an investigation of the Beast's appearances at the Brand Corporation. While he was working for Brand, he and Patsy grew distant and got divorced. Baxter had the Squadron Supreme capture the Avengers, and held them prisoner at a Brand facility. Baxter confronted his ex-wife Patsy, and was forced by Hellcat to release the Avengers from Brand captivity.

Baxter later allowed Roxxon, the company to which Brand was a subsidiary, to experiment on him and mutate him. As Mad-Dog, he became a mercenary, and directed Mutant Force. He invaded the wedding of Daimon Hellstrom and Patsy Walker to abduct Patsy and the Defenders. He was defeated by Daimon Hellstrom, and placed in S.H.I.E.L.D. custody along with Mutant Force. However, he escaped with Mutant Force. He became an agent of the third Secret Empire. As security chief, he aided the Secret Empire and its leader, Professor Power, in an attempt to start World War III. Together with Mutant Force, he battled and was defeated by the Defenders.
