>>53589782Game Guzma grabs at his hair when he does his "Guzma what is wrong with you" flipout after losing a battle. Manga Guzma slammed his head into the ground until his sunglasses broke and the lenses cut him. Not that that stopped him, he stopped because a grunt restrained him. He had his own Cosmog from Lusamine he used to open Ultra Wormholes at his whim, and just reveled in the chaos as the Ultra Beasts indiscriminately destroyed Po Town and attacked Team Skull too. Then he got abducted by one of the summoned Nihilego, and eventually washed up on a beach. Game Guzma described being controlled by it as being the first time he ever felt fear. Manga Guzma recounts it: "When I was with it... Wanting be acknowledged, to be taken seriously, or to win... None of that mattered. It just felt good." And when the Nihilego started fusing with Lusamine instead of him: "That Ultra Beast didn't even look at me. It just took her in. But... I didn't feel frustrated or jealous. Not even that much desire was left in me."
But he's not a total piece of shit! Guzma once stopped Team Skull from hassling Hau and treated him to hot cocoa at a Pokemon Center afterwards, and told Hau some about his frustrations with Alola. There's only one way to be, if you don't fit, tough luck. He offers to make him good hot cocoa if he comes to Shady House, because he doesn't even like the the way they make it in Alola. While getting medical care after the Nihilego thing, Guzma tells Hau not to wind up embittered like him, and to even leave Alola if he feels constrained by the expectations of being a kahuna's grandson. In the epilogue, Hau has a malasada and hot cocoa shop with Guzma and Mallow. It's like the only panel where Guzma doesn't look insane or depressed and it gets referenced in art of him a lot too.
tldr he's a fucked up asshole even to his own gang, but he sees himself in Hau and wants better for him, and they eventually get to make their own place to be fulfilled in Alola.
