Who is bigger arceus or groudon?

In the Pokémon universe, Arceus is generally considered to be larger than Groudon. Arceus has a height of 10 feet (3 meters) and a weight of 705.5 pounds (320 kg), while Groudon stands at 11 feet 6 inches (3.5 meters) and weighs 2000 pounds (907.2 kg). However, in terms of height, Groudon is taller, but Arceus is depicted as a more significant deity-like figure, often considered the "Original One" in Pokémon lore. Thus, the perception of "bigger" can vary depending on whether you consider physical dimensions or lore significance.
