Battle of Alderaan (TOR) re-fought with a twist
Alderaan is overrun with Sith troops and The Republic and Jedi are barely holding a small part of the system. Malgus figures the battle is virtually over. Instead of Satele and the commandos ambushing the Sith troops, without warning 200 ODST are dropped exactly into the combat zone. Master Chief (along with 2 other Spartans supporting the ODST) leads the ambush and his target is Malgus. Sith troops are baffled due the MJOLNIR shields holding against blaster fire. Malgus is caught unawares by John-117's speed and is forced into a physical contest.
All UNSC troops weapons have been upgraded to Republic standards. Can the Sith troops hold or are they overrun by the best troops the UNSC fields? Can Malgus defeat the legendary Spartan?
*Hopefully the moderator will allow this because all characters are seen in novels and short films.
