(This is a fan-made bacteria in a game called "Bionix".) Tardigrada Marine is a huge microbe with a big pair of legs, and all of that quite chubby. Tardigrada Marine is probably one of the heaviest bacteria due to it being slow. It cannot steadily run unlike everything else. It has overall 8 legs, a 2 sided thin tail, 2 antennas and a mouth. However, it's known to have heavy strength that it can even lift a Hydra or even a Tardigrade.
