Grosskopf started playing bass at the age of 15 when he became friends with a drummer and a guitar player. They were looking for a bass player, so he bought his first bass and started jamming with covers of the Sex Pistols, the Ramones, and the like. They covered songs from the Sex Pistols, the Ramones, Sid Vicious, XTC, The Stranglers, and others. Some time later, he decided to leave in hope of finding a heavier band with more live playing opportunities, then he met Kai Hansen and his band Second Hell, with whom he started playing. The band soon joined forces with former Powerfool guitarist Michael Weikath and adopted the name Helloween, with the original lineup being Kai Hansen (guitars/vocals), Michael Weikath (guitars), Grosskopf (bass) and Ingo Schwichtenberg (drums).
Grosskopf writes some of the band's songs, which were initially mostly used as B-sides, but since Rabbit Don't Come Easy (which contained 3 songs credited to Markus), tracks written by him are regularly present on their albums.

He played on Uriah Heep members' arranged orchestral version of Salisbury released on vidéo in 2001.
He also worked with the band Kickhunter, which released in 2002 their first album Hearts and Bones on which Markus played the roles of bassist, guitarist and producer, then again on the Little Monsters album released in 2007. His most recent endeavour is his bassguitar-focused side-project, Markus Grosskopf's Bassinvaders.

Grosskopf's playing style has been known to include prominent basslines, and occasionally he has a solo such as in "Heavy Metal (Is The Law)" or "Eagle Fly Free", which is one of his most famous. He is known to use both his fingers and a pick, depending on the song. He regularly uses a pick for the more straightforward, simple bass lines, as in I Want Out or Just a Little Sign, and fingers for more lead-type playing, as on Eagle Fly Free or Halloween.
His playing style expanded on one of Helloween's more recent albums Keeper of the Seven Keys - The Legacy, where many more bass solos and lead parts are heard, like "Invisible Man", "Light the Universe" and even some slap bass on the first single "Mrs. God", as well as "Goin' Home" from Pink Bubbles Go Ape, where one can hear slap for the first time in Helloween's discography.
Regarding new ideas for the songs, he was quoted saying to the Metal Insider: "Sometimes I shout them into my mobile phone wherever I am at whether it be on a toilet, backstage, or somewhere else. There is a big collection of riffs and more saved up and I plan to sort all these out when I get home."
