Bulbapedia doesn't show the Togepi line getting SM Dizzy Punch, but it could be wrong. It doesn't show it on Dizzy Punch or Togepi's generation 2 moveset.
#192 Sunflora The Sun Pokemon is all on one line bolded in Sunflora's page.
Tornadus has Rain Dance as level up and TM (both forms).
Shuckle has Bug Bite twice in its level up moves.
Shellder and Cloyster have Whirlpool as level up and HM.
Caterpie/Metapod/Butterfree have Electroweb as a BM, it should be MT.
Wormadam-Sandy gets Stealth Rock as an MT but not TM, so it should be small font italics for Wormadam-Trash but normal for Wormadam-Sandy.
In Form Differences under Wormadam, in the TMs section, it lists Swagger for Wormadam-Sandy and Wormadam-Trash, but Wormadam-Plant gets it too so it shouldn't be listed at all. However, Bulldoze should be listed for Wormadam-Sandy.
Ability: Multitype: 30% chance to heal status every turn.
^ Arceus' abilities. Not what Multitype does.
Larvesta and Volcarona have String Shot as level up and BM.
Durant has Dig as level up and TM.
On the main page Stunfisk is spelled Stunfish and the link therefore doesn't work. Credit to a season for noticing this.
Genesect's SpAtt stat is listed as 336, but it's 339.
Poison Touch seems to be wrong on every Pokémon that has it. It's user's contact moves, and (according to Bulbapedia) has a 30% chance of working (except in Japanese versions of BW).
Deoxys gets SM Nasty Plot
Phione doesn't have a Story Rank listed, unless it's only available through the park for some reason.
Cleffa only has Substitute listed as a small font italics BM, it should also be a TM under generation 4.
Munchlax and Snorlax have After You as a BM and MT.
Solosis, Duosion, and Reuniclus have Snatch as level up and MT.
Foongus and Amoonguss have Toxic as level up and TM.
Heracross has Aerial Ace as level up and TM.
Edit by Ataro: All fixed.
Magnemite/Magneton/Magnezone all have Sub listed as both a TM and a MT.
The images for Frillish and Jellicent don't show up for me. They seem to have the right url, but maybe you didn't post their images?
Edit by Ataro: Fixed.
Carvanha is spelled wrong in the main list, thus making the link not work. It's spelled right on Sharpedo's page, though.
Phione/Manaphy have Whirlpool/Dive as level up and HM.
Rapidash and Fearow have Pay Day as an SM.
On Delibird's page Pay Day is shown as one word, it should be two (it's under SMs).
Escavalier should have Shell Armor, not Shed Skin.
Magikarp gets SM Dragon Rage and SM Hydro Pump (though apparently not until 3/20) (though both are level up for Gyarados, but we all know there are perma Magikarps in URPG!)
While we're at it, Riolu only gets SM Aura Sphere
Tropius has SolarBeam level up and TM.
Rattata has Pursuit twice in its level up moves. Raticate apparently doesn't though. Pointed out by some region.
Deino/Zweilous/Hydreigon have Hyper Voice as level up and MT.
Tropius has Headbutt as BM and MT.
Deoxys gets SM Detect.
More moves that are available by different methods to preevos, but still available:
Happiny: BM Metronome
Murkrow: TM Swagger, TM Dark Pulse
Totodile/Croconaw: SM Hydro Cannon
Cyndaquil/Quilava: SM Blast Burn
Chikorita/Bayleef: SM Frenzy Plant
Squirtle/Wartortle: SM Hydro Cannon
Charmander/Charmeleon: SM Blast Burn, BM Flare Blitz
Bulbasaur/Ivysaur: SM Frenzy Plant
Seedot: BM Razor Wind
Munchlax: BM Selfdestruct
Pineco: BM Toxic Spikes
Fixed. Will not be inserting moves that can be learned by pre-evos with different methods as of yet.
Under Gengar's MTs, there's a < instead of a comma
The new version is now up. All the Pokemon entries are now in the /dex directory, but I have some redirection code thing so your previous links should redirect you to the new page. Bar Mr. Mime and Mime Jr.
AND ALSO. The site is best viewed in Mozilla Firefox, and to a lesser extent, Google Chrome. Chrome messes up with some of the height and width between the evolution/forme change boxes, so they may appear to be a little jumbled up, but other than that Chrome is perfectly fine as well. I would really prefer not for you to use Internet Explorer, but if you must, not only are there the earlier mentioned bugs, it also adds an ugly border around the sprites for forme change Pokemon.
You might want to either refresh (F5) or clear your cache if you're still seeing the old one.
Electivire has Giga Impact level up and TM.
Eelektrik and Eelektross have the same rank. I think Eelektross is supposed to be Merciless and Special, but idk.
Edit by Ataro: Fixed.
And now complete with a custom error page! How cool is that Squirtle.
