Enchantment: Merlin can cast spells to imbue a subject with magical properties.

Shapeshifting: Merlin possesses a well-developed ability to shape-shift as he was able to change into a fish, a squirrel, a turtle, a hare, a caterpillar, a walrus, a mouse, a crab, a goat (all of which were blue), and a germ.

He often references his knowledge of the future when speaking to others, leaving them understandably confused.

Foresight: He shows an ability to see into the future, though not completely.

Magic: As a wizard, Merlin shows a wide variety of powers and is generally hailed as being the greatest and most powerful wizard in the world.He wears glasses and his signature attire is a long blue vestment and a pointed wizard hat. Looks-wise, Merlin has the appearance of an elderly grandfatherly-type gentleman with a kind face, white hair, and a long white beard. Despite his wisdom, he can be absentminded and forgetful, as well as clumsy, with his long beard often getting tangled up in whatever he might be doing. He also warns Arthur not to believe that magic will solve every problem. He is a very wise character who believes in the philosophy of 'Brain over Brawn.' To this end, Merlin values education as opposed to the war-training philosophies shared by much of the rest of society. Merlin is a wizard of unspecified origin, who is first seen living in a forest cottage. He also met Madam Mim and became a bitter enemy to her.

It is unknown how he acquired his pet owl, Archimedes, but he certainly gave him an education, which he would later attempt to pass down to Arthur Pendragon, a feat of which Merlin seems to be proud. Merlin is a wizard of unspecified origin who is first seen living in a forest cottage.
