A Heroic Warrior with an oversized metal fist as his right hand. Hand-to-hand combat specialist; in modern continuities, the long-lost brother of Man-At-Arms.
Fisto is the Heroic Warriors’ hand-to-hand combat specialist, his right hand replaced with an oversized metal fist. The 1984 Mattel figure featured the iconic giant-fist sculpt as a literal play feature for punching at other figures.
The 2002 MYP series established his personal name as Malcolm and revealed him to be the long-lost brother of Man-At-Arms (Duncan), a relationship that has been retained across modern continuities including Revelation.
