It's definitely best that Tom was left unexplained. We humans (or maybe just me personally) love being mystified by unexplained, other-worldly powers and beings. Tom is presented as someone both powerful enough to take the ring and protect it, but also someone who'd forget about it and lose it in a swamp. He's not playing by the rules that Tolkien established for the rest of the characters in the books. He could have power beyond comprehension, or zero power, because Tolkien just didn't know what to do with him. But it's up to the reader to make that decision. Is he One Punch Man, or is he really just a nobody?
