|The following is based on Fallout 3 cut content and has not been confirmed by canon sources.|
The fists lack an in-game name and show up in the Pip-boy as <MISSING NAME>. With the fists equipped, you will never make contact with a target while swinging; no damage will be dealt and they will not turn hostile or otherwise react. They also lack a Pip-boy icon and a world model, so they use the default icon and do not show up when equipped.
This item cannot be obtained through normal gameplay, but can only be obtained through console commands.
