There has been talk within WWE of a possible Asuka heel turn, according to Dave Meltzer on Wrestling Observer Radio.
Meltzer added that WWE “has plans” for Asuka and re-iterated that he “heard that she might turn.”
The consensus on the internet is that Asuka has been used pretty terribly since being called up to the main roster and she seems to be going nowhere, so a heel turn would probably be good for her.
