 Despite his best intentions, Crichton makes enemies; the primary of these is known as Scorpius.There are a few stand-alone plots but the show gradually unfolds progressive arcs beginning with their recapture by the Peacekeepers, followed by Crichton's search to find another wormhole back to Earth and an eventual arms race for wormhole technology weapons.Secondary arcs explore the way in which the characters change due to their influences and adventures together, most notably Crichton over his obsession with wormhole technology, his relationship with Aeryn and the neural clone of Scorpius that haunts him in his brain.
