Azte was the founder and first emperor of the civilization that his descendant Mountezuma had been ruling until Quaxalcroc rebelled against him. He was a beloved leader and now, his spirit has been reawakened to regain power for his dynasty.
Skill "Cazte'm All" is a reference to the Pokémon franchise's tagline, "Gotta Catch 'Em All".
Azte's spirit was reawakened by Mountezuma placing a jewel inside a hole in an ancient statue.
As Azte was known as a fair and beloved ruler, it is unclear whether he will defend Mountezuma's shameful rule for the sake of his dynasty's continuation.
