Xerneas, Yvetal, and Zygarde; creatures of Viking lore
In Norse Mythology, Yggdrasil is the massive world tree, which connects all nine realms of Norse cosmology. The tree is also home to several creatures, including a giant eagle that perches at the top of the tree; the stags named Dáinn, Dvalinn, Duneyrr, and Duraþrór, who feast on the tree’s bark; and a wyrm (a dragon or snake-like creature) named Níðhöggr, which eats the tree’s roots. In the Pokemon world, these three creatures find their equivalents in Xerneas (the stag,) Yvetal (the eagle,) and Zygarde (the wyrm.)
Groudon and Kyogre of the Bible
The Book of Job mentions two enormous creatures: the leviathan and the behemoth. The leviathan is a sea monster, while the behemoth is a land monster. Here are a few lines from Job chapter 41 that describe the leviathan: “Who dares open the doors of his mouth, ringed about with his fearsome teeth? His back has rows of shields tightly sealed together… His snorting throws out flashes of light; his eyes are like the rays of dawn. Firebrands stream from his mouth; sparks of fire shoot out. Smoke pours from his nostrils as from a boiling pot over a fire of reeds… His undersides are jagged potsherds, leaving a trail in the mud like a threshing-sledge. He makes the depths churn like a boiling cauldron and stirs up the sea like a pot of ointment.” On the other hand, the behemoth is thought to either be an elephant or a rhinoceros, but some creationists opine that it’s the Bible’s version of a dinosaur. Job chapter 40 describes it as: “Behold now behemoth, which I made with thee; he eateth grass as an ox. Lo now, his strength is in his loins, and his force is in the navel of his belly. He moveth his tail like a cedar: the sinews of his stones are wrapped together. His bones are as strong pieces of brass; his bones are like bars of iron.” Their Pokemon equivalent are Groudon (the land creature, which raises land forms and expands continents) and Kyogre (the water creature, which can bring forth storms and floods,) both are legendary Pokemon.
