Trip's Serperior

Trip's Serperior (Japanese: Shooty's Jalorda) is Trip's starter Pokemon.

History
In BW001, Trip had recieved Serperior when it was a Snivy. He was then used to battle Ash's Pikachu and defeated it with Leaf Tornado due to Pikachu being unable to use any Electric-type attacks at the time.

It was revealed by Cilan that Trip's Snivy had already evolved into Servine and used it to defeat Chili's Pansear in Straiton City's Pokemon Gym.

In BW010, Trip used him again to battle Ash's Pikachu, who was now able to use any Electric-type attacks. But despite this, he was able to withstand Volt Tackle with Cut, thus defeating Pikachu again. Against his Snivy, he was revealed to be male when he was affected by her Attract and then defeated by Vine Whip and a powerful Leaf Blade.

In BW031, Trip used him again to battle against Snivy a second time. This time, Trip revealed that he trained him to deflect Attract with Leaf Tornado and then defeats the Grass Snake with a quicker and stronger Cut, and won.

He later evolved into Serperior for preparations of the Pokemon World Tournament Junior Cup where he fought Burgundy's Darmanitan. During the battle, he used Leer and then defeated it with SolarBeam, allowing Trip to enter the second round. In the next round, he defeated Marufuji's Heatmor and won using the same motives. He battled Cilan's Crustle and defeated it by avoiding X-Scissor and finishing it off with a powerful Frenzy Plant, allowing Trip to make it to the final round. He defeated Ash's Pignite using its powerful speed, Dragon Tail, and a powerful Frenzy Plant, allowing Trip to win the tournament and giving him the chance to battle Alder. Against Alder, Serperior was unable to defeat Bouffalant due to the Sap Sipper ability that Bouffalant had and lost in the process.
