Shockwave (Lancaster Sneed) is a fictional character in the Marvel Comics Universe whose first appearance was in Master of Kung Fu vol. 1 #42.

Lancaster Sneed was born in Newcastle-on-Tyne, England, and is the nephew of Sir Denis Nayland Smith. Before becoming an intelligence agent for the British agency MI-6, he was a carnival performer. After he stole an experimental exoskeleton, he became the professional criminal and mercenary known as Shockwave. He conspired to kill his uncle and Black Jack Tarr, and first battled Shang-Chi. He was revealed as Smith's nephew, and was defeated by Shang Chi.

He apparently returned later, and Shang Chi thought he was fighting the real Shockwave but was in fact it was a robot duplicate being controlled by Doctor Doom. The real Shockwave was later brainwashed by MI-6, and attacked his uncle, and battled Clive Reston and Shang-Chi. Alongside Brynocki, Shockwave battled Shang Chi and Leiko Wu on Mordillo Island. When Brynocki turns against him, Shockwave battled Brynocki and his robots alongside Shang Chi, Leiko Wu, and Black Jack Tarr.

Alongside Zaran and Razor Fist, Shockwave later attacked the West Coast Avengers on behalf of the S.H.I.E.L.D. Deltoids, but was defeated by Iron Man and escaped. Shockwave attended the AIM Weapons Exposition, and battled Captain America alongside the other costumed criminals there.

Shockwave (Marvel) has not been a contender in any CBUB matches.
