Story
It should be noted of Marcus's importance to the team: he is often the one to finish a major opponent. Some examples are when he smashed SaberLeomon's fang, blasting his DNA through Belphemon's chest, destroying Craniamon's shield and shattering Yggdrasill's true form. These are all performed from when he punches the opponent with immense strength.

Marcus's DNA Charge seems to possess great potential: the most noticeable moment was in episode 45 when his revelation that his friends believed and trusted him to stop King Drasil/Spencer Damon, it created an aura that protected him from MirageGaogamon's Full Moon Blaster and Rosemon's Forbidden Temptation; instead of hurting him, it simply collided with the aura and propelled Marcus upwards (he had been falling at the time).

Five years later, he and Agumon still wander the Digital World, challenging strong Digimon.
