When Z and Kat came to Piggy looking for a Quantum Enhancer that could handle sequences on a molecular level, Stench and Thresher stepped in and forced Piggy to give S.P.D. one.  However, this Quantum Enhancer was infected with a virus that would allow Thresher to send Stench into the S.P.D. base, through the internet.

To allow this to happen without notice, Thresher used an Evil Giant Robot to attack the city and cause a distraction.  While this occurred, Stench was able to enter the S.P.D. Base and steal the Schematics for S.W.A.T. Mode.  From this mode, Stench gained a Power Mode Armor.

After being defeated by the Delta Max Megazord, Thresher was captured by the B Squad.  However, on the way back to the S.P.D. Base, Stench showed up with his Power Mode and managed to free Thresher.  Both of them managed to escape before the Red Ranger, with the Battlized Armor Sonic Mode, was able to fire a blast, Stench and Thresher escaped.

Back in their hideout, Thresher gained a Power Mode as well from the technology stolen from S.P.D.

Stench and Thresher then proceeded in robbing and stealing in New Tech City.  When the Omega Ranger first tried to intervene, Stench and Thresher proved they were too powerful.  Omega was barely able to escape by morphing back to his light ball form.  Then, even when both the Shadow Ranger and Omega Ranger tried to fight the evil two monsters, they were still outmatched, and the Rangers were then captured.

However, after the Rangers passed Silverback’s training, and Kat finished the S.W.A.T. Armor, the Rangers were able to break into the building Stench and Thresher were in and use their new Armor and the Delta Enforcer to free Shadow and Omega.  Together as a team, the B Squad Rangers were able to battle, and defeat Stench and Thresher with the S.W.A.T. Armor and Delta Enforcers. 

Both Stench and Thresher were placed into Containment Cards after being blasted with the Delta Enforcer’s Containment Mode Blaster.
