You can't; magmar is a leaf green Pokemon. Instead, fire red players will be able to find electabuzz outside the power plant. They are both two very strong Pokemon, especially when you evolve them in Diamond and Pearl.
If you do have leaf green, magmar can be found at the foothills(outside the cave) of mount ember.
Remember both Pokemon are fairly rare so you may have to wait a while.
You can't catch a Magmar on Fire red but you can catch Electabuzz. Leaf green can catch Magmar but not Electabuzz
Magmar is only available in Leaf Green so you must trade.
Firered can't catch magmar leafgreen can at mt ember in the grass.
i don,t think you can but if thare is improve my answer
you could only catch it in leafgreen at mt ember or trade
No but you can get one only from an egg that came from a magmar and a ditto.
Sorry you can't catch magby, but you can still breed magby with magmar.
You catch him at the Pokemon MansionNo, it is found in the patches of grass on Mt. Ember.You can find it in the Pokemon Mansion which is located on Cinnabar Islands.
You can't catch Magmar in fire red, only leaf green. Instead you can catch an Electabuzz which can be found in the power plant (surf north of Lavender town). In Leaf Green you can catch Magmar on Cinnabar Island. There's a mansion that boosts fire pokemon. Magmar can be found there but it's very rare.
u cant u have to trade with leaf green its impossible inless u go to game sharknope sorry only available in leaf green
No only firered can.
You can't catch this Pokemon in diamond or pearl. You need to migrate a magmar, and ditto in from Pokemon leafgreen version. (You cannot get magmar in firered) Once they have migrated, put them both in daycare. After a little patience, an egg will turn up in daycare. This egg will hatch into your magby. P.S In leafgreen, you catch magmar in the grass in Mt. Ember, and you can catch Lv. 30 ditto deep in the Pokemon mansion, on the island South from Pallet town. Hope this helped :D
