Maylene

General Info - Maylene's Dojo specializes in the Fighting type, so you can fight back with Flying or Psychic type moves. Although neither of those types is known for outstanding defenses, both have great attack and speed, especially Staravia and Kadabra/Alakazam. But if they get hit too much, expect them to go down quickly. It may be better to attack with a Pokemon that is resistant to Fighting type attacks that also has good defenses. If you chose Turtwig, your Grotle should fair pretty well. Of course, if you happen to have a Ghastly/Haunter from the Old Chateau on your team, this battle should be a piece of cake.

Another thing you should keep in mind is that most of Maylene's Pokemon come equipped with the Force Palm move, which is very strong and has that annoying ability to paralyze your Pokemon. So carry some super potions and paralyze heals.

Lv 27 (Fighting/Psychic) - Meditite is not a very big threat, so just take it out and move on to the bigger threats.

Lv27 (Fighting) - If you've battled any of the trainers on the gym floor, you probably know how annoying these guys can be. They have okay defences coupled with high attack, so be careful.

Lv30 (Fighting/Steel) - Lucario can be annoying with it's high attack and the multitude of resistances given to it with it's steel type, mainly Flying and Psychic. Now is the time to switch out that Saravia or Kadabra and bring in a Pokemon like Monferno or something with a Fire or Ground type attack. Try to withstand it's attacks, heal when necessary, and preserver.
