Who would win? Bill Cipher or Godzilla Ultima?

Bill Cipher, a powerful interdimensional dream demon from Gravity Falls, possesses abilities such as reality-warping, mind control, telekinesis, immortality, and the power to manipulate time and space, while Godzilla Ultima, a monstrous Titan from the Godzilla: Singular Point universe, boasts regenerative abilities, adaptive evolution, immense physical strength, an atomic breath capable of disintegration, and the capacity to destabilize reality with his mere presence due to his connection to the Archetype phenomenon.
