[...Uh-] He was at the Lake of Rage in Johto, and the leader of all the other Magikarp and Gyarados. He was a lot bigger than the rest of them and the only one that was red.

Someone was hurting him, so he got angry and started rampaging. The other Gyarados started rampaging along with him. I didn't want anyone to get hurt, so I caught him. The rest of the Gyarados calmed down when I did.

He grew really close to me because I helped ease his pain. My best friend helped me catch him, so Gyarados is really fond of him too. [That's... That's the not Team Rocket version. Yes. Blue doesn't need to know about Team Rocket- at least not now.]
