Wrythe

Wrythe is a mercenary for Mandelbrot sent to capture Alec Wagner. His first attempt failed miserably. 
 
His second attempt was a better one and he brought some back up. He nearly achieved the defeat of the Split-Second Squad but Alec disobeyed his orders from Commander Hazard and rescued them. 
 
It was on this particular mission that the dimensional gate closed behind them. Alec created a new gate, but in the process of escaping they lost a teammate, Teah. 
 
Teah may remain alive and was used as a bargaining chip to get her boyfriend Trystan to betray Alec. If she is alive, she was captured by Wrythe.
