The successor to the RollerBadnik, the Roller mk.II model is a red and black incarnation of the armadillo-based Badnik. It also has yellow V-shaped ears and cartoonish eyes with black pupils.
Roller mk.IIs appear exclusively in Mirage Saloon Zone Act 1 (Knuckles' version only) and 2. Like the original Rollers, they will, in gameplay, curl into a ball and attempt to attack the player. Unlike the original Roller, hitting a Roller mk.II in ball form by either jumping or rolling will not hurt the player. Instead, the Roller mk.II will bounce off the player and uncurl.
A simple Spin Attack while it is not in a ball will be enough to defeat this Badnik. Upon their destruction, they release an Animal.
This Badnik's red and yellow color scheme, as well as the animal species it is based on, give it a resemblance to Mighty the Armadillo. Additionally, the sound effects used by the Roller mk.IIs are based on those heard in Sonic the Hedgehog CD and Knuckles' Chaotix, the latter of which Mighty was playable.
↑While not listed in any instruction manuals, the internal files in the PC release of Sonic Mania refers to this enemy as "RollerMKII".
