Forry and Empoleon is great, but no one uses it. Although after Empoleon's recent revamp, it may get more attention.

Nothing else will work over Forretress. The other good Toxic Spiker, Tentacruel, shares the Electric and Ground weakness with Empoleon. And Roserade is great for a sleeper, but otherwise is crap. And Forretress gets Pseudopass abilities should you wish to use them.
Feel free to fool around with the EVs on Forry, depending on your needs. These are used to optimize the situations in which Forry can set up, allowing him to go to work on many weak special attackers while not sacrificing much physical bulk.
You may wish to use a Swampert or Heatran to take the Fire atacks aimed at Forretress. But be warned: using a Heatran along with Empoleon will add to the Ground and Fighting weakness.
In addition to this, Cresselia is a choice for its resistance/immunity to Fighting/Ground attacks. In a similar vein, you may wish to try Salamence, as Intimidate can help it beat Lucario as well, but his overall defenses are rather mediocre. Gyarados is another option, but the Electric weakness is worrying.
