Homelander vs. 100x the Mountain from Game of Thrones

Fight to the death. All 100 Mountain clones spawn at the same time. Both sides are bloodlusted, fighting in an empty grassfield, and get 1 hour of prep time.

The Mountains each get their sword from the series and armor that's resistant to Homelander's heat vision. Homelander can still kill them with heat vision, but he has to get right up in their face to do it (close enough for the Mountains to grab him) or take their armor off. Homelander gets no additional weapons.

Who wins?
