'Sure." Liam said. A Trainer stopped them and challenged Liam to a double battle. He said they were each allowed to use three Pokemon. The trainer called out Raichu and Seviper.
Liam calls on Nincada and Cynder. 
"Raichu! Use Thunder Wave on the Quilava! Seviper, use Poison Tail on Nincada!" Both attack hit, the later doing only a small amount of damage.
"Nincada! Dig Cynder Defense Curl!" Both Pokemon did as instructed. 
 "Volt Tackle and Poison Tail on the Quilava!" The trainer called. Both attacks hit, the former critically and activated Blaze. "Now Nincada, attack Raichu, and Quilava use Flamethrower on Seviper! Both attacks hit. 
"Raichu, use Iron tail on Nincada, Seviper, use Poison Tail on Quilava!" both moves hit, KO'ing Cynder. Liam recalled her and was about to send out Staravia when he noticed Nincada was glowing. Nincada split into two sources of white light as it finished evolving. There were now two Pokemon sitting there.

"[i]Ninjask, the Ninja Pokemon, and the evolved form of Nincada. Its cry leaves a lasting headache if heard for too long. It moves so quickly that it is almost invisible. It congregates around tree sap.

Shedenja, the Shed Pokemon. A discarded bug shell that came to life. Peering into the crack on its back is said to steal one's spirit. A most peculiar Pokémon that somehow appears when a Nincada evolves. [/i]"

"Got to love, two-for's." Liam said with a smile.
"Shedding, use Shadow Sneak,on Seviper, Ninjaask, use Swords Dance." The two Pokemon did as instructed. Seviper was knocked out and replaced with a Pidgeotto. 
 "Double Shadow Ball on Raichu!" Liam called. The tag move KO'd the electric rodent, leaving only Pidgeotto.
 "Steel Wing on Shdenja!" The trainer called. The attack fazed right through Shedenja, much to the trainer's shock. Liam explained that Shedenja has an ability called Wonder Guard, and only super effective moves can pierce it. "Now, Giga Impact!" The physical hyper Beam KO'd the bird, and gave Liam the win. Liam went and healed his team and returned to Shiranui, ready to move on. Still unknown to them, Shinx was following but at to far of a distance for them to notice.
