FYI : In page 5 , she is cosplaying Sun Wukong , and the Earth Dragon is Buddha . That is a scene from the novel "Journey to the West" :
"After Sun Wukong caused havoc in the Heaven , the Jade Emperor appeals to the Buddha . Buddha bets that Sun Wukong cannot escape from Buddha's palm. Sun Wukong smugly accepts the bet.
He leaps and flies to the end of the world. Seeing nothing but five pillars, Wukong believes he has reached the ends of Heaven. To prove his trail, he marks the pillars with a phrase declaring himself the great sage equal to heaven (and in some versions, urinates on the pillar he signed on). He leaps back and lands in the Buddha's palm. He is surprised to find that the five "pillars" he found are in fact the fingers of the Buddha's hand.
When Wukong tries to escape, the Buddha turns his hand into a mountain. Before Wukong can lift it off, the Buddha seals him there using a paper talisman bearing the mantra Om Mani Padme Hum in gold letters. Sun Wukong remains imprisoned for five hundred years."
In short : Sun Wukong doesnt have the power to even jump out of Buddha's hand , and Buddha can crush him like an insect .
But there is something wrong with page 5 : When Wukong meets Buddha that time , he hasnt worn that golden magical circlet on his head yet . He gets that circlet from Tang Sanzang , 500 years later .
BTW , the artist probably "borrowed" the design of Jinouga / Zinogre from Monster Hunter when he drew the Earth Dragon .
