@CLManiac I'm not sure if one exists.
I would suggest posting in help section asking for help to add the portrait, or we can move this thread to help if you change what you are asking for.
Please also post a link to the cassie cage version you want it added to, and the portrait you want to be added. I'm sure someone will be able to assist
https://mugenmultiverse.forumotion.com/f10-mugen-helpPlease follow these rules when making a request.
1) The request section is not for requesting something to be made for you. It is for requesting Mugen creations that have been made already that you need help trying to find.
2) Try your best to give the creation name, as well as the creator's name in the subject of the request topic you make.
3) If you do not know either of those things, ask in the "Does this thing exist?" topic.
