Las Plagas vs. The Flood

The disease from Halo called the Flood comes down to Earth and infects half the world. The Las Plagas disease from RE4 returns and also infects half of Earth. Unfortuantely, this fight happens thousands of years later after Master Chief and Leon die so nobody is gonna defend Earth while these two evils go at it. Who ever wins will have all of Earth.

Which shall win and which shall fall?

If it takes place by day then The Flood will have a huge and overwhelming attrition advantage. If by night then Las Plagas soak up The Flood’s damage and defeat them.
