Yesterday we posted some news from Japanese magazine CoroCoro which not only confirmed the existence of Alolan Grimer in Pokémon Sun And Moon but also hinted at details relating to Jangmo-o and Type: Null's evolutions.
Scans of these evolutions have now appeared online. Jangmo-o's evolutions are Jarango & Jararanga and Type: Null's is called Silvadi.
According to Serebii:
When Type: Null finds a trainer it trusts, it destroys its helmet and evolves into Silvadi. 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.
