This is a very hard battle.
It really depends on what Megaman and Samus have. Are they at full power? If so, Samus wins (she's literally invincible at full power, and one Phazon shot kills anybody if they don't already have it in their system). If not.......well, it depends on what they have. Master Chief is kinda the weak link here, as he's simply not up to power with the rest. Although, he could get Cortana to hack Megaman, and then presto, it IM Vs. Samus, MM, and Chief.
