So I know like everyone has probably already seen the new stuff by now but here it is anyway:
Xerneas is a Fairy-type with the ability Fairy Aura (powers up Fairy-type attacks) and signature move Geo Control, while Yveltal is a Dark-and-Flying-type with the ability Dark Aura (powers up Dark-type attacks) and signature move Death Wing.
Pancham's evolution is known in Japan as Goronda, it is the Aggressive Pokemon and stands 2.1m tall. It's a Dark-and-Fighting-type with an ability called Iron Fist and can learn Hammer Arm. Its evolution from Pancham is triggered by a new process that isn't described.
The squid Pokemon are part of the same family and are known in Japan as Maika the Rotation Pokemon and its evolved form Karamanero the Reversal Pokemon. They're both Psychic-and-Dark-type and have moves such as Hypnosis and Turn Over (the latter reverses stat changes). They can have Suction Cups or Contrary as their abilities.
The pink bird is known in Japan as Shushup, the Perfume Fairy-type Pokemon. It has the ability Healer and knows AromaTherapy. It joins the previously-revealed seahorse Pokemon Skrelp as a Y-exclusive.
The orange-clad people are Team Flare (or Team Flair, translation is unclear). They are the "Team Rocket" of the game and their sole purpose is to use Pokemon to make money.
The gentleman on the right is the Professor, his Japanese name suggests he will be Professor Platane (which is French for Sycamore). He actually battles the player from time to time.
The white puff-ball is known in Japan as Peroppafu, the Cotton Candy Fairy-type Pokemon. It has the new ability Sweet Veil which prevents allies from falling asleep. It learns a new moves called Drain Kiss. It joins the previously-revealed shrimp Pokemon Clauncher as an X-exclusive.
The two people on the bottom are Gym Leaders, on the left is stufforon (snicker), and the other is Zakuro.
Just some additional images and the legendary figures people get for pre-ordering through CoroCoro
