Type: Null's evolution, Silvadi. When Type: Null grows to trust its trainer, it breaks its mask and evolves. It's ability is AR System, an ability that changes its type based on the "Memory" item. It also gains a new attack called Multi Attack, which is similar to Judgement its type changes based on the held item, but in Silvady's case, "Memory" is the deciding item instead of the plates.
Personal note: Silvadi looks amazing! Definitely one of favorite Alola Pokemon thus far. It looks pretty majestic without that mask. I'm sure to put one on my team, especially for that Arceus-like ability.
Jangmo'o evolves into Jarango and then Jararango. Both are Dragon/Fighting-types. They can learn Sky Uppercut.
Personal note: They both look good. I prefer the middle-stage at the moment, while the final evolution will take some getting used to. They might go on my team if I need room.
