Bloxxerman - HOURS

Rain and sun are illustrated by the open spaces outside the Stage. The sun is seen along with explosive drops against the ground. Planting a non-existent rainbow. [..] A guy falls from the stage's aerial entrance, crashing into the ground causing a shockwave in the center of the field, he looks up and stands up without saying anything. Sunglasses are visible on his face, a gray-tinted head, and a visibly disinterested mouth. Who do you think it is?

It's not Builderman, that much is made clear. He then attacks with a direct burst of Nails after taking a few steps in random directions.
