Vee

Vee is one of the many Pokemon Red obtained. He was caught by Team Rocket and experimented on gaining him the ability to change into Jolteon, Vaporeon, and Flareon without the use of a stone. This ability also hurt him and gave him pain. Red encountered him and fought him with Saur's help. Red and Bill realized there was something wrong with Vee and took him to a nearby healing machine and Red connected him to a healing machine hoping it would help heal him. Red realized Vee's past and was determined to protect him even fighting the gym leader, Erika who pretended to be one of Team Rocket's members also getting to keep Vee. Vee is seen again with Red helping him. Later, Red discovered that Vee was captured by Team Rocket again for more experiments. Later, Red rescued him after the evil Sabrina had no use for him and was going to dispose of Vee by killing him until Red appeared. Vee helped fight bad guys with Red. Vee later evolved into Espeon and this meant he was unable to change into Jolteon, Vaporeon, and Flareon. Now an Ex-Member of Team Rocket, Sabrina asked Red how Vee was doing and Red showed Vee as an Espeon to Sabrina and told her he was glad Vee wasn't able to feel the pain anymore. Vee was seen one last time interacting with Green's Ditto.
