In Pokemon FireRed and LeafGreen, Diglett can learn Dig at level 17, which is a nice and early level for a good move.
diglett or dugtrio
Diglett, Dugtrio etc, any ground type pokemon.
golem numel/camerupt diglett/dugtrio other ground Pokemon
If you are trying to catch Cresselia I would swap Diglett for one of our stronger Pokemon (click x then go onto the Pokemon section, click the Diglett and press switchto switch it for one of your stronger Pokemon before the battle). Diglett cannot learn Mean Look, or any of the other blocking moves such as block and Spider Web.If I were you I would use different Pokemon to catch Cresselia.
Any animal that can learn dig, like a ground type (gible)
I know Trapinch can learn it, Diglett can also. sandshrew too Edit from Anonymous: And Mightyna to!
Ground is super effective against electric type Pokemon. In Pokemon Red, it's wise to pickup a diglett from the diglett cave just east of vermillion. Or a sandshrew, and learn it the dig TM.
you can't permanately get entei to stop fleeing, but you can use mean look(crobat and golbat and jynx can learn it),fight entei with a Pokemon that has shadow tag(wynaut and wobbufet)or fight entei with a Pokemon with arena trap (diglett and dugtrio,but has to be from diglett's cave,which is in kanto)
I think it's a TM or maybe something between lv.15 and lv.30
arena trap-diglett. shadow tag-wobbuffet. block-snorlax
dark Pokemon can on learn thief in firered
no
