Cannot be Normal Summoned/Set. Must first be Special Summoned (from your hand) while you control a "Scrap" monster. If Summoned this way: Target 1 "Scrap" monster you control; destroy that target. If this card is destroyed by the effect of a "Scrap" card and sent to the GY: You can target 1 "Scrap" monster in your GY, except "Scrap Orthros"; add that target to your hand.
