Arceus (Pokemon) - Arceus is implied to be the creator of the Pokemon universe, making him the first pokemon technically. Despite him being catchable, and being considered a Pokémon, his origin is unknown, making him thr most mysterious entity in the universe.

God (South Park) - In one of the episodes of the show, the God is revealed to be a cat like thing with head and feet of a Hippo that is way smaller than his son, Jesus.

King Liniere (Panty and Stocking) - Father of Panty and Stocking, who rules Heaven with his wife. He looks like a bearded man, but he is unique enough to get a pass. His lower body looks like a sculpture with his junk hanging out at all times, which makes him look kinda funny.

Theories that suggest that character may be a godly entity or has powers beyond comprehension, sometimes beyond it's own understanding or knowledge, basically being Gods who don't realize their own godliness.

Sienduk's Winnie the Pooh theory - Russian Youtuber by the name of Sienduk, proposed a theory that Russian Winnie The Pooh is a godly entity who is able to bend his own reality to his will. Theory states that due to Christopher Robin's absence in the narrative, which would technically make all characters non-sentient plushies, Winnie became the ruler of his own world, and is capable of shifting reality however he wants. The theory also implies that Winnie doesn't actually realize that he has unlimited power, and that he doesn't know how to control it. Like how animation error of him falling of a tree, landing on a branch that he landed on before, could be evidence of him being able to teleport. Or how a bush he lands on after the fall, transformed into a puddle for him to use as a body paint to disguise as a cloud, like he subconsciously manifested the puddle when he thought of the whole "Operation: Cloud" on his walk to the tree. Another fun detail he mentions is that in second episode, where Winnie, Piglet and Rabbit are dining at the table, the table is drawn using Reverse Perspective, which is used in Orthodox Christian Iconography, with three characters representing Father (Winnie), Piglet (Son) and Holy Spirit (The Rabbit). Even though the theory is mostly meant as a joke, still fun to think about.

Alex Bale's Cars theory - Theory states that Mater's tall tales imply that Mater has ability to manifest his tales into reality. The evidence being that despite in his story about being an astronaut he clearly had his blue paint job, somehow Lightning McQueen was accompanying him through the adventure, even though it wouldn't be possible, since they only met when Mater became rusty and brown. The theory implies that Mater is a godly entity that doesn't realize, or at least acts like it, that he has powers of manifestation.

Tom Bombadil being a God - Tom Bomabdil is a character from Lord of the Rings, who doesn't seem to have too much plot significance. Despite that, he is said to be one of the most powerful entities in the world, despite being some weird bush guy living in the woods. Despite Tolkien stating that Tom is not a God, many people say that he may be something similar. But to be fair, even Tolkien doesn't really know what he is supposed to be, only describing him as a "spirit of vanishing countryside".
