|Artwork of an Au-Au from Mega Man 6|
Au-Au is a seal-like guard robot enemy that originates from Blizzard Man's stage in Mega Man 6. It is stationary and can throw big snowballs to the player character.
If the player is above or below Au-Au on the y-axis, Au-Au will be in a "passive state" and do nothing.
If the player is level with Au-Au on the y-axis, Au-Au will enter an "aggressive state", gradually create a snowball projectile above its head, and then launch it in the direction of the player.
If the player is no longer level with Au-Au on the y-axis while the enemy is in its "aggressive state", it transition back to its "passive state" after it finishes attacking.
The snowball projectile will not hurt the player while it is in the process of being created by the Au-Au. The snowball projectile is limited in the angles it can fire, and can't be fired beyond the ranges of 15 degrees diagonally upwards or 15 degrees diagonally downwards. The snowball projectile can be deflected with Shine or Proto Man's Shield.
Au-Au will turn to face the player, if the player happens to get behind the enemy.
- Au-Au's name is meant to resemble the sound that a seal makes.
