— According to a source, Kane’s return with the mask was not done to break the Guinness Record for most character masks in one place at WrestleMania. WWE had previously hinted, through their magazine and other outlets that they were looking to break the record. With injuries to Rey Mysterio and Sin Cara, many automatically assumed that Kane returning with the mask was an effort to salvage that. One source within WWE stated that if they are still interested in setting the record that they could just have Rey show up at WrestleMania, hand out masks to those in attendance and ask everyone to put them on to set the record.
— Kane is still listed on the WWE SmackDown roster but his profile photo has been updated with the new look.
