The Bacteria

The Modern Timeline
The Bacteria is a wolf-like creature, who claims he is "that .01 percent of bacteria that isn't killed by hand sanitizer". He is a joke character in the franchise, who has very zombie-like movements, and is the tallest character in the timeline, which is the subject of a joke at one point. Specifically about how he'd work in a fighting game. The Bacteria is very weird in terms of design, as he is a muscular anthropomorphic wolf with blue hair.

Sandbox: Essence Reading
The Bacteria currently has his essence detected, showing that he is alive.
