Huh, weird. Well, I was going to say something about how I briefly gave up on the DBS manga and decided to stop buying the physical volumes until the Super Hero adaptation sees print release in America, but... uh, it turns out Volume 18 isn't even out yet in the States anyway....
So we get some flashbacks here showing Burdock as a Good Guy, which I can't really use as ammunition against Toyotarou since Toriyama himself already pulled this in the Broly movie. We learn Burdock spared Granolah, his mom, and Monaito back in the day, but Elec killed Granolah Okaa-san, and Burdock had to fight Gas for a bit (which we don't really see yet, but I think will show up next volume). Granolah now knows the truth, so Goku and Vegeta let him fight Gas on his own. Elec has meanwhile gathered the two Dragon Balls off-panel to give Gas the same wish as Granolah, which is kind of wack, but whatever; I've resigned myself to tolerating these stupid "I wanna be the strongest guy!! xDD" wishes for the same reason I view the power-levels of the Saiyajin and Namek arcs as somewhat clever - the whole thing here is that "the strongest" is an ever-changing concept, as dudes grow with experience in battle, so it's not nearly as silly as it seems on paper, just as the whole point of Freeza's army's Scouters is that they're worthless when the Dragon Team are capable of suppressing their power, or exponentially magnifying it in the case of Kaiō-ken.
This volume is kind of weird for being largely Granolah versus Gas. That is, I've seen Super Hero, and Granolah isn't mentioned at all, so if he survives this arc he won't become a main character anyway, so... like, really, Goku and Vegeta can fuck off any time. They aren't really needed. The volume ends with Gas about to attack Goku because he's the spitting image of Burdock, and I guess generally speaking Goku and Vegeta always look for excuses to fight strong dudes, but it's almost pointless here.
It's funny to me that Gas "transforms" by first getting taller. The claw things around Gas's forehead were a power limiter, which allows him to transform differently after Elec removes them, but there's briefly a feeling that Gas's suppressed power is what makes him into a manlet, and that using the Dragon Balls for a power boost makes him taller because the wish can't just knock off his physical limiter device.
I guess it's also funny that Gas (Forma Alta) is initially matched by Granolah transforming into Forma Camiseta (by which I mean, like Jiren, Granolah gains power by losing clothing...?).
Granolah's mom pretty foine. Can't recall if I said that earlier.
