You Called? (phenomenon)
It is revealed in Mr. Time that Dang's ability to pop out of nowhere is thanks to his ability to slow down time, at the exact same speed as the machine that Adam created in the same episode. He is seen to walk around at normal speed, weaving between Echo and Mr. Tater, who are stuck in a slower time. To Adam and Derby, he is seen normally, as they are in a room which has extremely accelerated time, however to anyone else he can not be seen as he moves so fast.
