Invasion Of Two Army's (Mha X Halo Crossover)

Something has crashed on earth, but it wasn't a meteorite. The pro heroes have discovered a nasty but powerful parasitic lifeform in the crashed ship. This lifeform is known for growing and reproducing by feeding on sentient life in the galaxy. But they weren't the only disturbance however. There's also an alien race that is planing something to use the Halo rings for bad. After a devastating attack at U.A. high by the parasitic lifeform, the entire class was aided by an organization called the United Nations Space Command or the UNSC and now half the class went with a strong SPARTAN to put an end to the double trouble.

Since this fanfic is mixed in with Mha, most of the UNSC will obtain some sort of quirk, however our well known halo characters which is Terrance Hood, Avery Johnson, Miranda Keyes and Master Chief will be quirkless, but still strong.

This will take place in Halo 2 and Halo 3 events but some events from Halo Combat Evolved will be mentioned as well.
