If this answer is unsatisfactory, please tell me and I'll hide it. You just haven't made it very clear what you want in your answer, a lot of the converted posts answer your question yet you want them removed anyway. My answer is the same as the ones you've had removed:
Generation 6 does not have a #000 glitch Pokemon.
The first thing I want to mention is that glitches do not happen in a pattern. This question seems to assume that Gen 6 has a #000 glitch Pokemon just because every other generation does, which is a silly assumption as glitches are unintentional and any pattern is coincidental. Gen 6 is also much stronger and professionally made compared to many of the other Pokemon games, making it less likely that a glitch Pokemon will be present.
Clear proof of this can be seen on this Bulbapedia page; it lists all the Pokemon with the PokeDex number or hexadecimal identifier of 000 (glitch or no glitch). One quick look at the page shows that there is no Pokemon with 000 in Gen 6:
>By regional Pokédex number, 000 may refer to:
>- Missingno., a glitch Pokémon in Generation I whose Pokédex number is 0
- 'M, a glitch Pokémon in Generation I whose Pokédex number is 0
- $, a glitch Pokémon in Generation I whose Pokédex number is 0
- g g, a glitch Pokémon in Generation I whose Pokédex number is 0
- ???, a glitch Pokémon in Generation II whose National Pokédex number is 0
- ???, a glitch Pokémon in Generation III whose National Pokédex number is 0
- -----, a glitch Pokémon in Generation IV whose National Pokédex number is 0
- Victini, the first legitimate Pokémon with this number, in the Unova Pokédex
While it's possible that we are not aware of a glitch Pokemon with that number, it's still highly unlikely. X and Y have been around for over a year, and they have over 12 million players who could all find a glitch Pokemon with 000, but they haven't. It's true that Gen 6 is hard to hack, but it has been hacked before (e.g. Smealum who revealed Diancie, Hoopa and Volcanion and Project Pokemon who datamined the OR/AS demos). So I doubt that a #000 glitch does exist, because we most likely would have found it by now.
As mentioned by someone in the comments, OR/AS having a glitch Pokemon with #000 is a possibility, but even that is still unlikely. The OR/AS demos are modified versions of Alpha Sapphire that still contain most of the info from the full games (hence how everything here was discovered), so any glitch Pokemon is likely to have been found in their code when they were datamined.
Also, Hoopa and Volcanion are not #000, in case anyone is wondering this. They are already confirmed to be #720 and #721 respectively.
Bottom line is that there is no #000 glitch Pokemon, or none have been found yet. This is honestly the best answer I could find, and probably the best one you're going to get, sorry. :/
