The early life and origin of the villain known as Psynapse remains unclear, although it has been hinted that he and his fellow Dark Riders were lesser members of the Royal Family members of the Inhumans.
He was an original recruit of the Riders of the Storm, and he remained with the team until its hunting of the mutant Mesmero, where an error on Psynapse's part caused the team to question his fitness and seemingly kill him according to their ideology. Somehow reappearing as a part of the team once more, Psynapse was among the group under its second organization under the leadership of Stryfe.
He was killed in a confrontation with the mutant known as X-Man when his attack reinvigorated X-Man's mental powers.
The Dark Riders later resurfaced, hunting down and killing mutant healers as they believed their powers to be a violation of the natural order. This led to a battle with Magneto and the X-Men, as Hurricane and his team had targeted Elixir. The Dark Riders were eventually defeated, and Magneto killed the group by detonating explosives on their island.
