A new Pokemon Omega Ruby and Alpha Sapphire trailer has been unveiled, and it further highlights the newly introduced Mega Evolutions from this month's CoroCoro leaks.

The first Mega Evolution to be revealed in these CoroCoro leaks is Mega Lopunny, a Normal/Fighting dual-type with boosted Attack and possibly Speed. Its ability is Scrappy and also learns the move High Jump Kick.

Next is Mega Altaria, a Dragon/Fairy Pokemon with the Pixilate ability. This Pokemon Omega Ruby and Alpha Sapphire Pokedex addition will have boosted Attack and Special Attack, a true powerhouse!

And the final Mega Evolution to be revealed this time around is Mega Salamence, which will have increased Defense and the Aerialate ability.

This trailer further highlights Pokemon Contests, showing the trainer's ability to Mega Evolve if the appropriate Pokemon maxed out its appeal.

In addition, a new feature will be introduced, wherein gamers can use the 3DS camera to insert themselves into the Pokemon Contest Stage. Further more, the Pokemon Omega Ruby and Alpha Sapphire trailer also confirms the return of horde battles.

"My shiny competitive Salamence is aching for that Mega Stone!" commented Pokemon Global Link on YouTube.

"Honestly, these are some of the least ugly looking Mega Evolutions that have been put out," wrote Drake McWhorter on August 11.

"Mega Salamence is probably the only Mega I'll end up using," said Zephyr Alpha. "Its ability, combined with its move pool and the fact that it's Mega, is going to get itself banned by Smogon for sure."
