The Pokémon Company recently revealed an all-new Dusk Form for Lycanroc, which will be one of the new additions to the upcoming Pokémon Ultra Sun and Pokémon Ultra Moon versions. Eagle-eyed trainers will notice characteristics from both of Lycanroc's forms in Dusk form, including his eyes turning red when he attacks.
According to a post on the official Pokemon website, Dusk Form Lycanroc is similar to the Midday Form in that both stand on four legs and have an obedient demeanor.
Players who grab either Pokemon Ultra Sun or Ultra Moon within the first two months of the game being available will be given the Pokemon as a free gift via Nintendo Network. The Pokemon will also come with the Tough Claws ability, which grants an attack boost to physical moves that make direct contact. In Pokemon Sun, Rockruff evolves into the Midday Form of Lycanroc, while in Pokemon Moon, Rockfull evolves into its Midnight Form.
Pokémon Ultra Sun and Ultra Moon will be released worldwide on November 17th. If you actually want to get your hands on this form, however, you're going to have to use a special early purchase bonus.
