Agnes Chu, senior vice president, Content, Disney+ previously talked about the series saying:

“Giving new and existing fans the final chapter of ‘Star Wars: The Clone Wars’ has been our honor at Disney+, and we are overjoyed by the global response to this landmark series. While the Clone Wars may have come to its conclusion, our partnership with the groundbreaking storytellers and artists at Lucasfilm Animation is only beginning.  We are thrilled to bring Dave Filoni’s vision to life through the next adventures of the Bad Batch.”  

The characters that make up The Bad Batch include Hunter, Crosshair, Tech, Wrecker, and Echo, and here’s some additional information on them:

The squad consisted of four clone troopers designed with genetic mutations. “Crosshair,” a clone with brilliant eyesight abilities, “Wrecker,” a reckless clone with enhanced muscular form, and “Tech,” a clone with enhanced mental capacity and intelligence. They were led by Clone Sergeant “Hunter,” a clone with enhanced sensory abilities. Each member of the squad had a skull icon on their clone trooper armor, which could be seen as their unofficial logo and helped set the four apart from other clone units. They called normal troopers by the nickname “regs.” Following the Battle of Anaxes, Clone Corporal “Echo” joined the squad.

Clone Force 99 was named in remembrance of 99, a malformed maintenance clone who died while aiding the defense of Kamino from the Separatist invasion. The unit originated as a batch of clones who were born with “desirable” genetic mutations that made them superior soldiers. These mutations also had the unique effect of altering their appearance and voice greatly from regular clones. Each one of the members acquired certain abilities unique to the team. The team nicknamed themselves “The Bad Batch”. While part of the army, they earned quite the reputation. They were known to have a 100% success rate. The squad worked together with Marshal Commander CC-2224 on certain occasions, but did not report to anyone in particular.

Dave Filoni is executive producing the series along with Athena Portillo (Star Wars: The Clone Wars, Star Wars Rebels), Brad Rau (Star Wars Rebels, Star Wars Resistance), and Jennifer Corbett (Star Wars Resistance, NCIS) with Carrie Beck (The Mandalorian, Star Wars Rebels) as co-executive producer and Josh Rimes as producer (Star Wars Resistance). Rau is also serving as supervising director with Corbett as head writer.

The show will arrive on Disney+ in 2021.
