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.
You can catch red Gyarados anywhere because red Gyarados are only shiny but are extremely rare.
Use your super rod in sootopolis city behind the gym.Good luck!I found mine at level 38.
Yes, it is !
same chance to catch a shiny gyarados to catch eny shiny in platinum.
i think the Pokemon that evolves into gyarados is magikarp. it evolves at level 20
No
Gyarados is always a water/flying type, you can teach it fire type moves though.
level 45
In Pokemon Crystal version, you catch it at the Lake of Rage.
Gyarados is rare to catch, but you can try in the water of Sootopolis City. It's much easier to catch a Magikarp and evolve it into Gyarados at level 20. You can find Magikarp anywhere by fishing with the Old Rod.
train it
