ANY Pokemon that comes up as Pokedex number 000 is a MISSINGNO ok getit
any pokemon that comes up as number 000 is missingno!
Uh, no. If you read the page I gave you as well as
this one (and the link at the very bottom of this post), there's a definite difference between the two. First off, the effects of both glitches, including the fact that Decamark does
not duplicate items the way MissingNo. would. Additionally, Decamark only sports one type, can only be obtained by hacking the game, and is identified by the Pokedex. (MissingNo., however, was not.) Its moveset and stats are, likewise, not at all the same -- zeroes in everything, compared to the erratic stats of MissingNo. itself, and a moveset beyond the usual double Water Guns and Sky Attack of MissingNo.
Furthermore, allow me to pull a quote from the top of the page for MissingNo.:
Some other glitch Pokémon, even in later generations, have been referred to by people as a "MissingNo."; however, these aren't related to the Red/Blue MissingNo. in any way.
Yes, a
lot of glitches are labeled with 'dex #000. That's because the Pokedex literally does not identify them. However, in actuality, the term "MissingNo."
only defines the
original glitch in RBY. That is
that particular glitch's actual
name according to the game. It does
not describe the condition of missing a Pokedex number. Yes, that's what the term came from, but it's not a general blanket term. It's basically the difference between the terms "Bulbasaur" and "Pokemon." In this case, "MissingNo." is the species name, just like "Bulbasaur." It names a very well-known member of the group, but it does
not name the entire group because the games do
not name wild specimens all MissingNo. However, the blanket term for all specimens like MissingNo. is just "glitch," just like the blanket term for all unusual creatures with special powers like Bulbasaur's is "Pokemon." So, really, by calling every glitch (and almost all of them lack a 'dex number, actually) "MissingNo.," you're essentially doing the same thing as calling every Pokemon a Bulbasaur. Like I said, if the game does not call the glitch a MissingNo., then it's not actually a MissingNo. It most likely has different effects, stats, movesets, et cetera. You'd know about all of this if you spent some time studying them. (And yes, I've tested. I used to catch 'M and MissingNo. all the time. Though they're similar, I couldn't quite call them the same. Probably because MissingNo. didn't
evolve into Kangaskhan the moment I used it for battling the way 'M did.)
For a better example, most fans do
not identify 'M in RBY as the same thing, even though the two are both labeled as Pokedex #000. (They even actually look the same and are contacted the same way. However, they're acknowledged as not the same glitch.) Likewise, no one really considers Invisible Shiny Bulbasaur as being the same thing, yet it's got no actual 'dex number (or entry, for that matter).
But hey, if you don't want to believe it's not the same thing (even though I've presented you with a lovely site that says otherwise), then that's fine. I just found it odd that you claim to be a MissingNo. fanatic, yet you don't actually know the difference between glitches, apparently. (I was simply trying to tell you that your original question is fairly misleading because there
is no MissingNo. in RSE.) Just don't expect us to assume you're the leading resource on glitches when there's research out there already concerning every glitch in the book. *shrug*
Edit: But in case you didn't tl;dr the above, and you're still possibly with me,
have a glitch dex from one of the most well-respected resources for Pokemon glitch information on the 'net. Note the names, and yes, you can navigate to other generations using the links on the side. While it doesn't seem that later entries are populated just yet, the RBY list should give you an idea that not all Pokemon with missing numbers are actually MissingNo.
