When Type: Null finds a trainer it trusts, it destroys its helmet and evolves into Silvadi. While it is Normal-type as standard, there is a special hold item called Memory that lets it be one of all 18 types at any one time thanks to its ability, AR System. It's not currently known if it's one item that can change this, or if there are 18 different ones. The type change is reflected in its eyes, mane and tail which glow the colour representing the type. It has a new attack called Multi Attack which changes type based on its hold item
