(New X-Men I#116 - BTS) - After Professor Charles Xavier (secretly Cassandra Nova who had switched minds with her twin brother) came out as a mutant on live TV, the Xavier Institute was opened to the public. Marcus was among the many young X-gene active teenagers that enrolled.

(New X-Men I#117) - Marcus was one of the many students seen walking the school grounds after the Beast had introduced Xavier's latest student: Barnell Bohusk, codenamed Beak.

(New X-Men I#140) - Marcus was among the students and X-Men present when Bishop and Sage showed them the diamond bullet used to shatter Emma Frost's body, seemingly killing her in the process. With everyone still considered a potential suspect, the Summer holiday vacation was cancelled until the case was solved. Sage started analyzing and interviewing the student body, including Marcus. Bishop and Sage eventually solved the case and identified Esme Cuckoo as Emma's killer. A little while later, Beast was able to reassemble Emma's shattered diamond form which allowed Frost to restore herself.

(New Mutants II#7) - Marcus was seen walking through the school hallways when Josh Foley had finished his class with the X-Man Archangel.

(New X-Men I#149) - Recent X-Men recruit and teacher Kuan-Yin Xorn eventually went insane, believing himself to be the team's biggest enemy Magneto. Dressing like the master of magnetism, the Chinese mutant assembled a Brotherhood made up of his former students (Xorn taught a special needs class which included Angel Salvadore, Beak, Ernst and others). With them at his side, he laid waste to most of Manhattan. Outraged by "Magneto" and ready to fight back, Marcus joined other students to form an impromptu X-Men street team. Setting up camp in New York's Mutant Town he was present when the Three-in-One brought in Beak and discussed what was going on.

(New X-Men I#150) - Marcus was present when the Three-in-One engaged in telepathic crowd control. They also used their powers to keep Fantomex and Cyclops up to date on other developments while fighting Xorn. The X-Men street team was also present during the final battle where Xorn (still disguised as Magneto) killed Jean Grey by causing her to have a fatal stroke. Marcus later witnessed how Xorn was beheaded by Wolverine.

(House of M#8 - BTS) - Marcus was one of the many millions mutants who lost their powers when a reality altering spell cast by the Scarlet Witch reduced the number of gene active mutants to a mere 300 worldwide.
