Universe Tree Goku's ultimate will feature Xeno Goku. Which form should he be in

Sachant que c'est juste sa version super saiyan blue qui fait un kamehameha avec goku 4 xeno donc autant mettre la version du goku 4 limit breaker

If the transformation is smooth enough go with it. But if it's a bit tricky better without it

Whether he transforms into or not, LB must be involved in the Ulti. Quick question, do you know why some of your characters (most of SSJ3 and some others) are not affected by Json (mainly for auras) ?
