How do you defeat the sixth gym leader on Pokemon heartgold?

Answer 1

infernape is probably the best choice against him because he has bot fire and fighting type moves: mach punch is an efficient start & flamethrower/wheel is a good good follow up. other than that get fast fire,ground, or fight type Pokemon to annihilate his steel

Answer 2

It doesn't matter which Pokemon you use, as long as you stay tough, you will win. The gym is Ghost-type right? Get a Dark-type like Murkrow in Eterna Forest at night. Murkrow is only in Diamond. Misdreavus (Ghost-type) is in The Lost Tower under Solaceon town on route 209. You can get Misdreavus if you have Pearl only.

Answer

OPTION1

okay well i don't know if i got this by luck or what, but anyways use a Dark-type moves for ex. i have a Luxray lv.32(Shinx 2 and final evolution) in this battle all i did was use its move Bite, since that move was a "Dark Move" it beat all 3 of Fantina pokemons (Drifblim lv.32,Gengar lv.34,Mismagius lv.36) but Mismagius did fainted my Pokemon when it used "Magic Leaf"-(A Grass type move,Yeah i was suprise that this Pokemon had grass since its a ghost?) w.e its called,but i used a revive -(revives a Pokemon after a faint, that's why it got its name,no brainer;) ) at some point. Well hope this helps,goodluck.

OPTION 2

Fantina is the leader of Hearthome City Gym, the fifth gym in Pokemon Diamond and Pearl. She specialises in Ghost-type Pokemon, which shouldn't be much of a challenge for a good team.

Fantina has the following Pokemon:

Drifblim (Ghost/Flying) level 32

Gengar (Ghost/Poison) level 34

Mismagius (Ghost) level 36

A good team for this gym battle will involve a decent levelled team with Pokemon who have Ghost or Dark-type moves. As Fantina's highest level Pokemon is on level 36, I recommend that you have your team between level 34 or 36. Do not use Psychic-types, as they will not stand much of a chance unless they are on levels in the late 40s or early 50s (and even then). The best type to use against Fantina's Pokemon would be a Normal-type, as Ghost moves do not hit Normal-types. Conversely, Normal-type moves do not hit Ghost Pokemon, so have your Normal Pokemon learn some Ghost moves (like Shadow Ball) and/or some Dark-type moves (like Crunch).

Two out of Fantina's three Pokemon are duel-types, so be careful when sending out your Pokemon. Of course, you could play this to your advantage, using Electric or Ice-type moves against Drifblim.

The only strong move Fantina seems to have is Ominous Wind, which isn't too devastating, so your Pokemon will be alright. Simply keep your team on a decent level, and use type to your advantage.

Answer 3

Go to the light house and talk to the guy with the spiky hair. then go to the gym and use a ground type.

Answer 4

use any of your Pokemon and try your best

Any of your starters other than the grass one will do well. Also, electric, fighting or ground will also do well.
