She's a travel buddy from when I traveled in Unova. [flashback reveals Ash, Iris and Cilan alongside Pikachu, Axew and Pansage] She's on a journey to become a Dragon Master. It says she wants an official battle with me.
Iris is presently the strongest trainer in Unova. In other words, she holds the title of reigning Champion. [Since Iris is confirmed to be Champion by defeating Alder, it appears to also confirm that Trip failed his goal of defeating Alder. It's also confirmed that Virgil, the winner of the Unova League Conference, did not succeed in becoming Unova Champion as well.]
Following her journeys with Ash, Iris fought Dragon type trainers and Gym Leaders and met many Dragon types, learning all the time. By trusting in her Pokémon, she climbed to the position of Champion.
Oh, we lost our rhythm completely, didn't we? We must get our hearts in sync and become one with each other! Yeah, no more kid gloves! [she summons her...Haxorus?!]
That's right! And now it's my strongest partner! [Note: The reason Iris' Axew had to become Haxorus is because fans did not approve of the writer's decision of having Axew being kept in his base state throughout the Black and White series and making Axew get lost in the Unova League]
