for what i know is you can only get one. first, you have to have 8 gym badge and then defeat elite four; second, go to the relic castle and when you start going in, professor pokemon will go out to talk to you and then she will give one rage candy bar to you.
after you beat the game go back to the relic castle and Professor Juniper(girl) will walk out and tell you about the statues then she'll give you 1 Rage Candy Bar you use to awaken the statue.
From Professor Juniper at the Desert Resort.
And in the city of the 7th gym!!!!!
From a House in Iccarius City near the wind mill
from Professor Juniper after you beat N
go to Castle Ruins to gain it near the weird statues
You can get it in the seventh city, from the professor, in the Real Unova, and by defeating Cintia.
you dont
you find the red gyaradoes in the Lake Of Rage... but it is very hard to find just like all the other shiny poke'mon... and yes the red gyaradoes is a shiny poke'mon.
mean rare or rage candy bar?
use a super rod at the lake of rage.
He is at the Lake of Rage from 6am - 10am every morning.
When you find them, they fill your Rage meter. You can then use Super Moves.
you have to go to the guy blocking you from blackthorn city
The Ragecandybar is not obtainable in FireRed and LeafGreen.
you are only able to catch red gyarados in Silver/Gold versions in Lake of Rage or something like that, my point is you can't catch it in Leaf Green/Fire Red
You have to beat team rocket in goldenrod city before you can go to blackthorn city.
You can go to the underground path near Vermillion and talk to a man, who will ask you for the candy. In return, he'll give you explosion.
once u beat the elite 4, you go to kanto and go north of vermillion city into the bikers trail. there is a guy in the bike trail that will give u the TM explosion.
You use Ice path then come out at Blackthorn. I can't remember when but, eventually he will let you through. actually you have to go to the radio tower in golden rode and defeat the team rocket.
Graphs are visual representations of information: they are not capable of emotions, such as rage.
beat the other 7 leaders and take care of team rocket at the radio tower then take the path next to the Pokemon center in mahogany (it is blocked by a guy that sells you a rage candybar until the previous things are done)
at the lake of rage
lake of rage
you find a red gyrados at the rage lake
