"I was focusing on the fact that he is a survivor," Toyotarou said, "But Toriyama reminded us that this isn't a warrior race, right? But that they do like to fight... I didn't really know what to make of that."
"I kind of had the goal of turning him into a sniper," Toyotarou said, explaining Granolah's unique eyewear. "And with that, I could imagine that this was a race of sharpshooters, and so Granolah could have these goggles for locking on to targets, which just seemed really cool."
The artist also revealed that it was Toriyama's idea to have the goggles talk to Granolah. "Toriyama used to say that "If there aren't two characters moving together, we never know what they're thinking," Toyotarou said, adding that this idea is why the Supreme Kai is paired with Kibito and Beerus is with Whis.
"Since this race went extinct 50 years ago, even though they're aliens, I wanted a slightly old fashioned feel," Toyotarou said while describing the process of designing Granolah's clothing. "I also wanted some steampunk elements. That's how the clothing was designed... I wanted the race to feel kind-of old timey."
