In an interview with Entertainment Weekly, Star Wars mainstay Dave Filoni revealed that the Bad Batch is George Lucas' brainchild: "He wanted to explore this idea that there were clones that were a little bit more unique from one another that were like a special forces unit that had enhanced skills.... [without] making them superheroes." And indeed, each member of the team — official designation: Clone Force 99 — has a specialty. Those specialties set them apart from other clones — who they call "regs" — and allow them to tackle the most perilous missions imaginable.
While it's not entirely clear what sorts of missions they'll be tackling, it is clear from the trailer that The Bad Batch takes place after Emperor Palpatine issues Order 66. As anyone who watched The Clone Wars and Rebels knows, some clones were able to outmaneuver Palpatine's galaxy-wide command, so the question is: what about the Bad Batch? It's hard to tell from the trailer alone, but based on their generally freewheeling nature established in The Clone Wars, they may not end up subservient to the Galactic Empire — at least not without a fight.
The official synopsis on StarWars.com clearly states that they're trying to "find new purpose," but that could mean a lot of different things. No two clones are the same, despite their very nature (and often because of it, as The Clone Wars conveys time and again), and that's more true for the members of the Bad Batch than for any regs. We'll be sure to keep you updated as more information on The Bad Batch trickles in, so stay tuned.
