The Red Gyrados drops it. If you already fought the Red Gyrados, you should already find it.
Actually there is no red Gyrados. I mean there is, but a red Gyrados is a shiny Gyrados.
beating / catching the red gyrados in the lake
Gyrados's shiny color is red so if you ever find a shiny gyrados or magikarp catch it. Also at the lake of rage you can catch one that is already red.

Gyrados's shiny color is red to get a red gyrados is very hard it takes 8000 chances or so to see it keep finding gyrados until its red.
The red Gyrados is found in the Sendoff lake at the Spring Path.
you get a lvl 100 magicarp at the resort area, not a red gyrados
Use super rod at Lake Valor and eventually it will be reeled in
