I do feel Red Gyarados is just High Tier, anyway, he's maybe the best HM Slave of the game, but he's good at fighting stuff, but he's not that great on the Elite Four, he comes later, it's level-up moves are horrible, and it depends of Return (that will not have good power until really late on Kanto) to deal maximum damage (also, lol FE reference, I feel more as a Jeigen that Dugtrio LV31 on RBY than other thing).
