Many different suits/protection equipment would fit this scenario. Tardigrades survive various forms of extreme environmental conditions. A person in the picture could wear a spacesuit, a diving suit, a fireman suit, etc. In fact, explosions are perhaps one of the very few things a tardigrade wouldn't survive. But you probably chose that suit, because it closely resembles the appearance of a tardigrade? Some gas mask or a respirator would fit well to mimic the "mouth" of a tardigrade.
There could be one tardigrade on one side vs many people in different suits on the other. That way the art would emphasize that for a human to achieve resilience which this micro animal exhibits naturally would take using different types of extreme environment equipment combined. This would increase the fun element even more.
