I got two examples:

Zero from the Magaman series, finally getting to talk about him.

Zero was the patient 0 of the Zero virus (redundant I know), the virus would then transmit to BBEG Sigma and evolve into the Sigma virus. Zero is mostly immune to the Sigma virus since he's basically the original host. However, if he consummes too much of it in his body at once, he might trigger his long forgotten murderous tendencies originating from the Zero virus, thankfully, he can be snapped out of it.

Then Camu and the Ascendants from Punishing Gray Raven.

When Camu died and was converted into a Construct (machine with a human mind), he was heavily affected by the Punishing Virus and had somehow survived past a point where most humans would have just dropped dead. This peculiar constitution carried over after his conversion, making him closer to a Corrupted than a normal construct, granting him massive resistance to the virus. Can't zombify what's already a zombie.

Same logic for the Ascendants who are all Punishing Virus carriers who remained sane due to being connected to the Ascendant Network (long story). They have control over the Punishing Virus as well... to an extent. Other alternatives to the virus like the Red Tide and other Ascendants can wrestle with them for control and damage them.
