Silence

sound button is by them when they speak, they have a DVD player in their chest and whenever someone puts a disc in a hologram pops up and the movie appears... they can mute anyone they want, they just go to settings and mute the person speaking, they only go mute for them and no one else. they have a button on their wrist that pops up a hologram screen of basically a computer screen... and they can play games n stuff... they can drag stuff from the hologram screen into real life, like the trash option in Windows and spawn it and put trash in.. then drag it back to the hologram screen and it'll stay. they don't sleep, they need to be recharged after 15 hours or so. they can take pictures with their eyes and the image will come out their mouth.. they eat batteries for lunch and drink battery acid for liquids
