The Pokemon Company has revealed a brand new trailer for Pokemon Omega Ruby and Alpha Sapphire this morning.

Featured above, the new trailer depicts the recently confirmed mega evolutions for Salamence, Lopunny, and Altaria. I personally think that Mega Salamence and Altaria look a bit silly at this point, but then I’m reminded of mega Blastoise and his neck-mounted cannon.

Also revealed in the trailer were the five different cosplay outfits that you can don your Pikachu with, and you can even see Pikachu entering the fray in costume, sporting some unique moves!

Pokemon trainers will be able to get their hands on a Shiny Beldum holding a Mega Stone, if they buy either Omega Ruby or Alpha Sapphire at launch, on November 21st.

The actual handling of the distribution will be similar to how they’ve done previous promotions, which is via an internet connection. If you evolve your Beldum into a Metagross, you’ll be able to eventually mega evolve the Pokemon into Shiny Mega Metagross!

Finally, horde encounters were confirmed to be returning in Omega Ruby and Alpha Sapphire, only this time you won’t be encountering them in just wild, random Pokemon battles. This means that multiple trainers can swarm you and collectively assault you – in groups up to five. It’ll be interesting to see how this pans out!

Here’s the rest of the press blurb, for your viewing pleasure:

Be center stage at the Pokémon Contest Spectacular

Once players arrive at the Hoenn region’s Pokémon Contest Spectacular, they can enter their Pokémon in five different contest categories—Coolness, Beauty, Cuteness, Cleverness, and Toughness—in which the Pokémon is judged on one of these five conditions. For example, in a Toughness Contest, a Pokémon will display moves to show off its Toughness appeal. Demonstrating a move like Flying Press will get the audience excited, but using the move Play Nice probably won’t elicit the same excitement. The more excited the audience gets, the more the Pokémon will maximize its appeal.

After entering the Pokémon Contest Spectacular for the first time, Trainers will receive their very own Cosplay Pikachu, which is unique in that it knows moves that a normal Pikachu cannot learn and can use them in battle. For instance, Pikachu Rock Star knows the Steel-type move Meteor Mash, and Pikachu Pop Star can use Draining Kiss in battle, a Fairy-type move that is effective against Dragon-type Pokémon. Pikachu, Ph.D., can learn the Electric-type move Electric Terrain, while Pikachu Belle learns the beautiful Ice-type move Icicle Crash. Last but not least, Pikachu Libre can battle with Flying Press, a powerful Fighting-type move.

Players can enter Pokémon in multiplayer contests against friends, take photos of each show, and build a following of fans that will appear at each Contest Hall entrance and help a player’s Pokémon win future contests.

New Mega-Evolved Pokémon

Three new Mega-Evolved Pokémon have been announced today: Mega Altaria, Mega Salamence, and Mega Lopunny. Mega Altaria becomes a Dragon- and Fairy-type and receives the Pixilate Ability, which changes Normal-type moves into Fairy-type moves. Mega Altaria also receives big boosts in its Attack and Special Attack stats and an increase in its Defense. Mega Salamence’s Defense stat soars, and it receives the Aerilate Ability, which turns Normal-type moves into Flying-type moves. Mega Lopunny receives the Scrappy Ability, making Ghost-type Pokémon vulnerable to Mega Lopunny’s Normal-type and Fighting-type moves. Mega Lopunny also gets a huge boost to its Attack stat and a Speed increase, making it even more formidable in battle.

Horde Encounters return to the Hoenn region

The popular Horde Encounter feature from Pokémon X and Pokémon Y returns in Pokémon Omega Ruby and Pokémon Alpha Sapphire. This time, Horde Encounters will not be limited to wild Pokémon encounters, as hordes of enemy Trainers can now appear in groups of up to five, providing even more Experience Points to victorious Trainers.

Pokemon Omega Ruby and Alpha Sapphire is are coming to the Nintendo 3DS on November 21st in North America and November 28th in Europe.
