By Twitter Dr.  HyperCake Joker with Person 5, the first paid DLC character in the Super Smash Bros. Ultimate, discovered its stage through datamining.
Now this tag is indicated by both a rumor and a tag in case it is true, but in reality it is not very unexpected. If you do not want to be spoiled about what is potentially Jocker's official scene in the Super Smash Bros. Ultimate, come back right now!
In the tweet by Dr. HyperCake shows that the line "Jack_. Menentos »was found in the database of stages and corresponds to the format of the line for other stages. Also, according to rumors, Jack is the code name for the development of Joker.
Digging through LVD files to Ultimate, and I found "Jack_Menentoes_", which lies among the rows. The format of this line corresponds to the string names of the stage in ui_stage_db ("[Series] _ [Stage])), and the internal Joker is" jack. " Is the scene confirmed? pic.twitter.com/eCh3PxU2bR
