Yes, it is !
i think the Pokemon that evolves into gyarados is magikarp. it evolves at level 20
Gyarados is always a water/flying type, you can teach it fire type moves though.
level 45
Gyarados is probably the best, it is evolved magicarp.

A red gyarados is a shiny gyarados (however, the Pokemon Company did not call them shiny untill the Unova Region). You can find it wherever you can find a normal gyarados, but your chances to find it are very slim.
im not sure you could catch one in ruby because ruby is in the hoene region but gyrados belongs to the johto and kanto regions hope i helped
The Red Gyarados is unique among shiny Pokemon as it actually first appears as a part of an event. Players first encounter the Gyarados at Lake Rage and have a chance to catch it before engaging Team Rocket.
In Pokémon Ruby, Magikarp will evolve into Gyarados at Level 20.
Since Kanto, Magikarp has evolved into Gyrados at level 20.
Well, yes and no. You can find a shiny magikarp that will evolve into Red Gyaraddos at LV.21. You can't actually find any gyarados without codes. The red gyarados is shiny gyarados. There is a 1/3492 chance of finding shiny gyarados.
