Tarkus

Tarkus is an antagonist from Part I: Phantom Blood. He is a zombie made from the centuries-old corpse of a powerful warrior of ancient Britain. Unlike his ally Bruford, Tarkus was a typical strongman fighter and had sold his entire soul to Dio Brando.

History
Tarkus and Bruford were successful in The Challenge of the 77 in 1563 (two of only five challengers to ever succeed). Tarkus and Bruford were members of the Tudor Dynasty and retainers of Mary Stuart. Eventually they gave themselves over to save Mary from her rival Elizabeth I. However, Elizabeth's deception to make them surrender led to a strong sense of betrayal that made them susceptible to manipulation by Dio three centuries later.

Phantom Blood
The pair are resurrected as zombies by Dio so that they could oppose Jonathan Joestar, Will A. Zeppeli, and Robert Speedwagon. During Bruford's fight against Jonathan, Tarkus stands guard against Zeppeli and Speedwagon, preventing them from rushing to Jonathan's aid.

However, after Bruford's defeat, Tarkus shows little respect for him and promptly stomps on his armor, the final remaining signs of his friend's presence in the world. He also killed Zeppeli for attempting to help Jonathan, but was killed by the latter shortly after.
