I think Ness might be too much as well. Ness is quite busted. After collecting all of the Melodies, he created his Magicant. An entire universe inside his mind that contained the Truth of the Universe. After touching the Truth of the Universe, his consciousness overlapped with everything in the universe. Spacetime included. Making Ness semi-omnipresent. He also absorbed a portion of its power and gained unimaginable power and intelligence. The Truth of the Universe is said to be filled with the Ultimate Intelligence. Ness most likely knows every single PSI and PK ability. Can survive attacks against Giygas, the Universal Cosmic Destroyer, also able avoid his attacks. Ness even has the Truth of the Universe to bail him out if he gets killed, making it so it never happened or can pray to the Player who dealt the last hit to Giygas.
