Infection

Infections is a disease-based antagonist found in Doctor Robert Jacob. Infections come in three colors: crimson (Pyrexia, which can manipulate heat), blue (Vigor, which can manipulate cold), mustard (Bizarre, which can transform people into different shapes or species). The scarlet, blue, and lemon ones appear in every episode. To kill an infection, Robert Jacob must line up 3 Massive Aspirin of the same color next to the bacteria of that color. The plague, along with the Massive Aspirin, will then disappear. After clearing one patient of germs, Doctor Jacob moves to the next one, with each patient per episode having increasingly more Ebola.

Appearance
Infections resemble a sunbeam, being spherical with multiple spikes, as if rays. Pyrexias are a strong scarlet, inclining to indigo. Vigors are blue. Bizarres are a pale yellow, a little greenish.
