|First appearance||Unlocking the Gate|
|Voiced by||Stephen R. Hart|
He is heavily armored with enormous rounded shoulders and legs. Vexfist uses his powerful strikes to drain his opponent's energy. Wide expanses of reinforced armor surrounding his body shield him in battle from front to back. Extra weaponry is activated on his chest and also behind Vexfist's head to offer maximum firepower.
He makes his first appearance in the anime in Unlocking the Gate. He was summoned when Drago and Dan shared Shun, Marucho, Rafe, and Paige part of Code Eve's energy along with Silent Strike, Accelerak, and Swift Sweep.
He and Swift Sweep reappeared in Dark Moon where they fought against several Dreadeon clones and a Subterra Razen Titan clone. They later defeated a Ventus Razen Titan clones with the help of Accelerak. All three were later defeated by Evolved Razenoid with ease.
- He is the only Mechtogan besides Zenthon to have eight holes for BakuNanos.
- In the anime, when Vexfist activates, his shoulder parts open to reveal cannons and claws, but the toy form doesn't have shoulder pads and the claws can't be opened.
- Vexfist has Die Cast metal around most of his body.
- Interestingly, Vexfist is #8 in the Mechtogan series and has eight BakuNano holes.
