[Pokémon] How can Giratina exist in our world?

So, if you've played Pokémon Platinum or Legends: Arceus, you might know about the Pokémon Giratina, the third in the Creation Trio of Dialga, Palkia, and itself. Giratina is apparently supposed to represent anti-matter, and it lives in the Distortion World, which I believe is supposed to be an anti-matter alternate universe. But, if Giratina is anti-matter, the how can it exist in our world without tearing apart? And if Giratina is made of normal matter, but was banished to the anti-matter Distortion World, then wouldn't it tear itself apart? Maybe that's why it's Origin Form is a floating centipede, so it doesn't need to touch anything (opposed to the Arceus-looking Origin Forms for Dialga and Palkia)? Any insights would be greatly appreciated :)

Giratina changes forms whenever it travels between the two worlds, altering it's body to fit the world's physics, like say proper wings and legs due to the normal world's gravity, where in the distortion world the gravity is more chaotic, thus it doesn't uses it wings for flight but as tentacles to grab stuff. The Griseous orb creates a field that simulates the distortion world's environment, so it changes forms when wielding it.
