Ankiron

Ankirons are enemies that Wario encounters in the game Wario World.

Ankirons resemble huge armored turtles with cannons sprouting out of their shell. In fact, Ankirons are so huge and heavy that all they can do is turn in place. Ankirons fire cannonballs at Wario, who can throw the cannonballs right back. The cannonballs explode after a short time, however. Ankirons can also hide in their shells to protect themselves against Wario's powerful punches. If Wario continues to punch a protected Ankiron, it comes out (though still not harmable) and fires its ammunition (depending on species) in all directions.

Other varieties of these enemies include Skeletal, Circus, Ice, Bullock, Stuffed, and Mummy Ankirons. Aside from looks, Skeletal, Circus, and Ice Ankirons behave exactly the same way as normal Ankirons. The Stuffed variety can fire many cannonballs at once, while the Bullock and Mummy Ankirons shoot lethal, fiery cannonballs. However, the Bullock and Mummy Ankirons behave differently when they're attacked while protected, with the latter firing fiery cannonballs, while the former only fires normal cannonballs.

Wario also comments that they smell like feet in the official American Wario World instruction manual.
