Splash Woman is one of the 8 Robot Masters and a villainess from Mega Man 9.
She was created by Dr. Light for rescuing ships in the sea, designed with a mermaid motif which makes her an excellent swimmer and equipped with a trident which allows her to pierce tough surfaces. Because her expiry date had run out and she was scheduled to be scrapped, she, along with the other Robot Masters, is convinced by Dr. Wily to be repaired by him, but he instead reprograms her to serve him. She loves singing but is a bit scared of large crowds.
Splash Woman will swim around and sing to summon robot fishes, while firing off her Laser Trident. Once she goes to the top she will attempt to stab the player. Her weakness is the Hornet Chaser. She is last seen in the credits sequence posing for a photo.
