No, you can not, first catch a gible inside wayward cave underneath cycling road downward from eterna city, once inside use the TM flash(found in department store in veilstone city)find and catch gible then level it up to level of 24 witch will evolve into gabite, then level it up to the level 48 witch evolves it into the last evolution, GARCHOMP!
Go to victory road and on the bottom floor, you can find gabite at lv 45-48 and gabite evolves at lv 48 into 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.
Gallade is. Garchomp and Gallade can learn Dark Type moves, and Gyrados can learn Ice.
garchomp
if there levels are at least 65, pretty good[have you caught giratina, dialga, and palkia yet?]
Three of your pokémon are weak to Ground, you should try to fix that.
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.

You can't. You need to evolve Gabite.
Gabite evolves into Garchomp at level 48.
Sorry you can't catch Garchomp in the wild. Evolve It from Gabite. Gabite evolves at level 48 Gabite- Victory Road (Pokémon Platinum Only) Or you can catch Gible which can be found in Wayward Cave B1F Far Northwest of the regular entrance. Gible evolves into Gabite into Level 24
You can't, not without hacking the game.

Garchomp cannot be found in the wild, and nor can Gabite. Gible, however, can be found in the Safari Zone and leveled up to lv. 24 (Gabite) and then, once it is Gabite, lv. 48 (Garchomp).
