'Spider-Sense'. One of his first abilities that came forth, it gives Peter a sixth sense of sorts. If there is any threat that Peter thinks could harm him, physcially, mentally or any other 'ally', this 'Spider-Sense' (as dubbed the welder) will alert him of it. In his early years, it is not very precise and can be very vague but with some training, this ability could make him a formidable opponent.
