Personality/Bio

Overkill was Jack's very first Pokemon. He was a Magikarp that Jack stole from a restaurant tank when he was just seven years old. He tried releasing Overkill into the ocean, but he refused to leave and when he became a Gyarados, they became inseparable from each other, even though he had to stay secret from Jack's mother for a long time. Overkill has a fun, jolly personality, especially for a Gyarados. He likes to play around and swim with others, even letting people ride on his back. While normally fun-loving, he can become very serious if the situation calls for it.
