The series follows SAM (Kamali Minter), a robot hailing from the kingdom of Botica. SAM stands for "Special Associate Model," as she reminds us (and every one of her new friends) as she meets them throughout the show. She's on the hunt for her "very best friend in the world," Kelby, the Prince of Botica who barely escaped the kingdom following its harrowing invasion by a malevolent, larger-than-life magic and mech user, forcing the pair apart. After meeting up with a robotic junk mechanic named Casey Turnbuckle (Stephanie Sheh), SAM enlists the help of outlaw Philly the Kid (Kenny Blank) to take them to Gara's Keep. It's the only lead to where Kelby can be found, and when Philly reluctantly agrees, the trio sets off on a raucous adventure.
The way to Gara's Keep is paved with dangerous roadblocks, like a cannibal "mother and daughter" pair clad in leather made from, well, you don't really want to know. Then there's an entire outlaw gang with cybernetic body parts that resemble scorpions and insects, right down to a man with a beard resembling the arachnid. These colorful enemies aren't just "bad guys of the day," but living, breathing beings imbued with back stories and personalities you're dying to know more about, even when they're absolutely awful.
The trio's journey is facilitated by "Bessie," Philly's trustworthy ride that's seemingly operated by the arcade machine in its console. Deposit four quarters, and it can transform into a menacing raging bull mech that you don't want to mess with. It gets our heroes out of harm's way more than a few times, but car mode has a few tricks up its sleeve too, like a mounted machine gun on the hood. What's more, it's absolutely huge -- not only long, but tall, too, and appears to change sizes depending on the episode, which seems unintentional. That just makes Bessie all the more imposing.
The main cast steals the show, though. Philly the Kid is your archetypal "cool guy" outlaw. Shades of Trigun's Vash the Stampede and Cowboy Bebop's Spike Spiegel (as well as a bit of Mugen to boot) make up his gritty exterior, which belies Philly's slacker vibe. But there's one particularly interesting tidbit about him that you'll notice immediately: the line of numbers dotting the left side of his body. It appears that Philly is cursed, as you learn in the first episode, never to die. The numbers appear gradually on his body, counting the number of times he's been killed, as he comes right back to life afterward. What could this be about, and why is Philly now immortal? It's a secret you’ll have to keep watching to unravel.
