Well, that would be notable on its own. We've got a ton of Psychics, a ton of Something/Flyings, and a handful of other types as legendaries... If there were one that had a type that no other Pokémon had, that would be quite impressive
Also, what form would it be in? A Kabutops or Aerodactyl skeleton legendary? No thanks. If your saying they should turn the 'tetris block' form as the legendary, just no. How on earth would a block of messed up ixels make a good legendary?
Hey, who said it would make a GOOD legendary? :P
Now that you mention it, why choose one of the forms? Why not all three? Missingno: comes in Kabutops Forme, Aerodactyl Forme, and Tetris Forme. Having multiple Formes, that puts it among the lofty ranks of Deoxys, Giratina, Shaymin, and Arceus. (... as well as Burby/Wormadam and Cherrim. Oh well.) I like that idea, though.
Legendaries shouldn't evolve,
Who made that rule, anyway? That's really the only part of the arguments against Missingno that bothers me. Rowan points out that all known legendaries don't evolve, true, but nowhere in any canon does it state that having the power to evolve automatically excludes a Pokémon from legendary-status.
The word "legendary" indicates that "legends" arise around it. Legendaries are Pokémon that are so special in some way that myths and rumors spring up around them (or at least we're led to believe they must have myths/rumors), and thus, the gamemakers treat them differently by giving them their own overworld sprites, setting up special battles that you have to do to catch them, making them one-per-game (or occasionally, one-per-pair-of-games), and sometimes putting their images on the box art. If Missingno had its own OW sprite, if there were one per game, if you had to get a special item to summon it (like the key item Teru-Sama or something appropriately glitchy), if NPC OWs in Glitch City's Pokémon Center talked about the strange creature living off Seafoam's coast, and if Nintendo slapped a glitched-up Tetris block on the cover of a game, then Missingno would probably be a legendary, whether or not it could evolve into Rhydon.
But all these things (or most of them) can be true without the Pokémon being legendary. In G/S/C, Lapras and Red Gyarados meet most of these (they have their own OWs, people talk about their appearances, you meet them in special battles, there's one per game--although multiple normal Gyarados--and Surf is a prerequisite. Heck, Lapras is even non-evolving/evolved), but they aren't legendary. So there's no hard-and-fast definition.
You have to be kidding me...
Yep, pretty much. (I am, at least.) Missingno as a legendary would be very amusing--in concept. In practice, if Nintendo actually made it a legendary, 19.5% of the fandom would think it's pretty cool, 79.5% would be outraged and convinced that the Pokémon franchise had been RUINED FOREVER!! by this new idiocy, and 1% would find it hilarious but not really care about it either way.
Anyway, sorry for picking on your post in particular to reply to, but it had a lot of ideas I wanted to respond to. And thanks for the idea of multiple-Forme Missingno--even if you probably didn't mean to get the idea in my head, heh.
