Following Dr. Eggman's presumed death and the Nocturnus Clan's attempt to escape from the Twilight Cage, the Sentry Mk. IIs were found by the Nocturnus Clan, who took control of them and began using them as a part of their own forces. The Sentry Mk. IIs can only be encountered in the Nocturnus Clan's hideout in Mystic Ruins. Their basic attack is shooting a yellow laser at their opponent. Their POW moves are Evade and Buzz Saw.
