Iron Tail
Secret Power
Dig
Crunch
Maybe add a Citrus Berry too
Hyper Beam?
Mightyena doesn't learn the move crunch in Diamond and Pearl. I think it does in ruby sapphire and emerald.
Keckleon Mightyena Lombre Poocheyana learn the move by themselves!!
any fighting type move
earthquake
The pokemon move. ( It's super effective)
I think its Crunch or Dig or Double edge or Earthquake. I can higly recement Mightyena, for your Pokemon team!
icebeam is super effective
Any rock type move will be 4* effective, or hyper effective against Ho-oh.
ghost and bug
Any fire or flying type move will be "super effective"
The only way I know of to get a super effective hit on spiritomb is to have a Pokemon use foresight on it and then attack it with a fight type move.
No, but there are berries that can protect one of your Pokemon from super effective moves! Like if you have a dragon type, such as Salamence, and it is very weak to other dragon moves. If it is holding a Haban berry, before the other Pokemon uses a super effective dragon type move, the Haban berry will weaken the move! I don't really do this though...
