Vector is one of Ayden's Pokémon currently residing at Ayden's home in Phenac City. He was originally a very shy and weak Sandile but as he evolved, he became more powerful and confident in his abilities.
As a Krookodile, Vector is a natural fighter and can easily withstand the harsh desert environment he was raised in, making the Orre region feel just like home to him. He has excellent eyesight and can easily zoom in on distant objects. In addition, his jaws are powerful enough to crunch a car.
Vector originated in the area surrounding the Relic Castle in Unova. He was often alienated and excluded by the other Sandile for being smaller and weaker, resulting in an intense shyness and low self-esteem. When Ayden arrived in Unova, she was intent on catching a Sandile and evolving it into Krookodile. Many she encountered would escape by burrowing into the sand, but Vector was too afraid to do anything and simple stayed where he was. While under Ayden's care, he slowly grew more confident in his abilities and eventually became a fully evolved Krookodile just as Ayden had wanted.
He was primarily used by Ayden during her time in Unova and now currently resides in her home in Phenac City.
