Having evolved from his Prinplup in the run up to the Grand Festival, Empoleon was used during the appeal round. Like before, it is Kenny's powerhouse and has many powerful attacks including Metal Claw, Bubble Beam, Mist and Flash Cannon allowing it to be an incredibly strong Pokémon within Kenny's team.
Kenny's Alakazam has only been seen once, during his Contest Campaign in Floaroma Town. It has a variety of attacks at its disposal like Shadow Ball and Hidden Power so it can hold its own in battle easily.
Kenny's Breloom has only been seen once, during the Solaceon Contest, as well as during a training battle against Ash's Turtwig. It has many powerful attacks including Mach Punch, Stun Spore and Energy Ball at its disposal.
Machoke is another one of Kenny's Pokémon that Kenny utilized during the appeals process. As it was used in the appeals as opposed to battle, very little of it's battle skills are known as it just showed off it's physical strength.
Kenny obtained a Floatzel prior to the Grand Festival in Sinnoh. Floatzel has some powerful attacks such as Whirlpool at its disposal which it used in conjunction with Empoleon to create a dazzling appeal, however it slipped up during the appeal which caused Kenny to fail the appeal round.
