Luna looks like your typical Funtime animatronic with stars attached to wires behind his back. His left eyes is blue while his right one is green. He has a bright pink bow tie and a speaker in his chest. Different types of green appear on his body 
His appearance is more likely being Lunatic like between crazy and goofy since his voice acting way was like that the character came out from fnaf fangame called Animators hell he often can be silly but overtime can be dangerously serious..
