Iris's Axew (Japanese: アイリスのキバゴ Iris's Kibago) is the first Pokémon that Iris was known to have. He debuted alongside his Trainer in In The Shadow of Zekrom!.
Axew is the first Pokémon that Iris is known to have obtained. She obtained Axew from the matriarch of her hometown when Axew was just a few days old. She was given the task of journeying with Axew in order to help raise it into a great Haxorus.
Axew was the first Pokémon that Ash scanned with his new Pokédex in Enter Iris and Axew!, though he was actually aiming it at Iris's hair and wondering why Axew looked nothing like what the Pokédex showed. Axew appears to be a friendly Pokémon, making quick friends with Ash's Pikachu. They are shown to have a strong relationship such as in A Sandile Gusher of Change! where a Sandile had caught him in its jaws, Iris tried everything to get it out.
Axew has been shown to have some childish traits, such as in Saving Darmanitan From the Bell!, where he fought Pikachu when he thought Pikachu was the one who ate all the food. In The Bloom Is on Axew!, it was shown that Axew has not had much experience in battling, crying when he was hit by weakened attacks from Cilan's Pansage; however, he was shown to be able to produce an extremely powerful Dragon Rage that can cause massive destruction, but is uncontrollable and has a tendency to explode in all directions rather than beam at a specific target as is meant to. Both Ash and Cilan playfully refer to it as a "Dragon Sneeze", much to Iris's annoyance.
Axew in Iris's hair
In BW017, Axew seemed excited about Ash's Pokémon egg being ready to hatch; so much so that he accidentally sends it rolling down a hill. After it hatches into Scraggy, Axew becomes afraid of it after seeing how aggressive it was with the other Pokémon. Even so, he kept his eye on it and was the first to notice that it ran off in the middle of the night. Axew assisted Iris in finding a plant that would help Scraggy recover after it was paralyzed by a wild Galvantula. The next day when Scraggy felt better, Axew battled it. Both Pokémon ended up knocking each other out. The two have another battle in BW020, however it is stopped after Axew attempts, again, to use Dragon Rage.
Like Pikachu and Dawn's Piplup, Axew appears to prefer being outside of his Poké Ball (if Axew even has a Poké Ball), but unlike them, he likes to travel inside Iris's long hair, while Pikachu and Piplup usually go on their Trainer's shoulder.
A Japanese event randomly distributed an egg that contained an in-game representation of Iris's Axew, Ash's Pidove, or Cilan's Pansage via Nintendo Wi-Fi Connection. Like its anime counterpart, this Axew knows Scratch and Dragon Rage and is male. It also, interestingly, always has Mold Breaker as its ability. This event started on December 17th, 2010, and ended on January 11, 2011.
