Asuka is a WWE character.
She first appeared in BT Productions during the Looney Games Bloopers special "Royal Rumble Ravage". Like in WWE, it has been said that nobody is ready for Asuka. This scheme seems to have worked when she killed The Miz and got The Hurricane to commit suicide. However, Matt Hardy was able to kill her with a sickle. She is most well known for a former unbeatable streak of wins.
Like the other WWE women that got an icon drawn by BT Productions, Asuka's custom-made icon was retired when BrantSteele released its offical icon for her.
