Mudkip Theories #1 ---- Unown was originally a glitch.

In my opinion, Unown being a glitch would explain a whole lot. First, the very uncreative names. Yes, there are other uncreative names such as Farfetch'd, Stunky, Pidgey, Ditto, the list could go on for hours, but Unown? Unknown, with a k and an n removed. An abbreviation for Unknown. Like MissingNo is an abbreviation for Missing Number. This is my theory on how Unown came into existence.

       So, one day the staff at Game Freak were testing G/S or something, and they discovered a glitch Pokemon in the Ruins of Alph. In fact, it was the only thing that would appear. There were 28 forms. Some of the forms resembled letters, similar to MissingNo. They couldn't seem to get rid of it, so they changed its forms a bit to resemble letters, and with the two remaining forms, they made an exclamation point and a question mark, which still isn't very creative.

      So I think Unown was originally only there to occupy hexidecimal slots. Which is why it hardly seems like a Pokemon and has the crappiest name in existence. If you think you can prove me wrong, comment.
