The first images of the evolutions of Jangmo-o and Type: Null have been revealed through CoroCoro for Pokemon Sun and Moon, building upon the new info that was unveiled earlier this week. Jangmo-o evolves into Jarango and Jararanga, while Type: Null evolves into Silvadi when it voluntarily destroys its helmet after finding a trainer it trusts. A Normal type by nature, Silvadi has an ability called AR System, which allows it to be one of all 18 types at any specific time through a special hold item known as Memory. Expect to learn more about these new Pokemon later today, October 14. Check out the first images of them in the scans below:
