|Sprite of Yaffu from Mega Man Maker.|
Yaffu (also known as S-R300) is a fan robot with the capability to generate strong winds. Yaffu was originally designed to assist in the creation of movies by creating wind effects for specific scenes, but was modified for combat by Dr. Wily. They are enemies that originate from Mega Man 6 from Wily Stage 3.
When Yaffu spawns, it will use strong winds to pull the player towards it, pauses briefly to reverse its fans, then uses strong winds to push the player away from it, pauses briefly to reverse its fans again, and restarts its behaviour from the start, pulling the player towards it again. The facing direction of the black coloured arrows on Yaffu's body are an indication of when it is using its winds to push or pull the player.
If the player gets behind Yaffu, Yaffu will not turn around to face the player and will continue to manipulate wind in its facing direction. When riding an utility like Rush Jet or the Support Items, Yaffu can pull the player character off that utility.
- Yaffu functions similarly to the enemy Fan Fiend, who can push the player away with strong winds, but unlike Yaffu, can not pull the player towards it.
- Yaffu's contact hitbox becomes slightly wider horizontally in both directions, for the few frames of animation where it pauses briefly to reverse its fans.
- Originally, in Mega Man 6, Yaffu took extra damage from Beat.
