Marcus is a student at Metropolis University.
Season Four[]
Geoff Johns paid Marcus for his urine, needing it to pass an upcoming physical exam. Much to Geoff's annoyance, Marcus showed up at a wake for the recently deceased David "Coop" Cooper, wanting the money that Geoff owed him. Geoff used his metahuman ability on Marcus to scare him away.
Lois Lane later approached Marcus, having learned about him selling his urine. She started talking to him, but Marcus took off when Geoff came there.
