The emotion on the servbot mask you use to make the super slicer will appear on it.
The Super Slicer is featured as an avatar clothing item if you preordered the XBOX 360 version from Amazon.
If Chuck enters a cutscene while wielding the Super Slicer, Chuck will still be wearing it in the cutscene, even though it technically counts as a weapon. This also works with the Moose Head, the Burning Skull and the Beer Hat.
Due to an animation error, if you hold the aim button, the blades of the super slicer go into Chuck's back. This also works when the blades are spinning.
These are avatars that were supposed to be available if a player pre-ordered Dead Rising 2 for the Xbox 360 on Amazon, they include Chuck Greene's familiar motorcross outfit, and the Super-Slicer. This avatar outfit gives a cartoony feel to the weapon. They were never delivered.
