Macrophage Enemy POLL (Patreon)

We're approaching the end of Exa's model adjustments. Our game has a Hero, now we need to create her enemies. I haven't really decided what kind of germs or virus she's fighting yet. But, for a generic "Infection" enemy. What is your PRIMARY pick, and what is your close second? And, explain why in the comments if you can, It really helps to hear your thought process on these things :)
