You have to first catch a Gible, which you then evolve into a Gabite which then evolves into a Garchomp at level 48. You can find Gible under the cycling road to the North of Oreburg city. Then you cut down the trees, and go to the far side. There should be a cave entrance hidden under the bridge.
Garchomp cannot learn Giga Impact from leveling up in Pokemon Platinum. Garchomp can learn Giga Impact from the TM that teaches it which is TM68.
Gallade is. Garchomp and Gallade can learn Dark Type moves, and Gyrados can learn Ice.
garchomp
Three of your pokémon are weak to Ground, you should try to fix that.
if there levels are at least 65, pretty good[have you caught giratina, dialga, and palkia yet?]
The 111th Pokemon on Platinum is Garchomp.
Garchomp cannot learn Giga Impact from leveling up in Pokemon Platinum. Garchomp can learn Giga Impact from the TM that teaches it which is TM68.

On the real fire red that is impossible, as garchomp only exists in pearl, diamond, platinum, heartgold, and soulsilver. Firered only goes up to #386 Deoxys
If You Just Want To See A Garchomp For Your PokeDex, Champion Cynthia has one. If You Want To Catch One You Have To Evolve A Gible Into Gabite, Then Gabite Evolves Into Garchomp.
