I'm currently going through the creature database to identify missing mobs and NPCs.
The creatures listed below are all within the valid 0.5.3 ID range but currently have no spawn locations. Many of them are vendors, have loot tables, or are involved in quests, suggesting they may be missing. I've tried to exclude creatures that are only spawned temporarily during quests.
Most of these show up on the crawler: https://crawler.thealphaproject.eu/search/
This is a rare in Feralas who should be in the isle of dread.
https://db.thealphaproject.eu/index.php?action=show_creature&id=5343
Another Feralas rare who should be in the sea around Sardor Isle
https://db.thealphaproject.eu/index.php?action=show_creature&id=5345
Another Feralas rare
https://db.thealphaproject.eu/index.php?action=show_creature&id=5349
No spawn location. Should be in Wetlands / Hillsbrad?
https://db.thealphaproject.eu/index.php?action=show_creature&id=5185
https://db.thealphaproject.eu/index.php?action=show_creature&id=5043
- [ ] 6. Private Hallan (should be in Dustwallow Marsh?) (seems to be spawn during quest: Questioning Reethe)
https://db.thealphaproject.eu/index.php?action=show_creature&id=5045
- [ ] 7. Lieutenant Caldwell (also Dustwallow Marsh?) (seems to be spawn during quest: Questioning Reethe)
https://db.thealphaproject.eu/index.php?action=show_creature&id=5046
This guy should be in Booty Bay. He also starts a quest.
https://db.thealphaproject.eu/index.php?action=show_creature&id=4631
- [ ] 9. PROBABLY NOT MISSING: Grenka Bloodscreech (spawned by quest script?)
She should spawn during quest Test of Endurance. So not missing.
https://db.thealphaproject.eu/index.php?action=show_creature&id=4490&filter=Grenka+Bloodscreech&sort_order=name&pos=1&max=1
No location, no model
https://db.thealphaproject.eu/index.php?action=show_creature&id=4504
These two where likely located in Dustwallow Marsh.
https://db.thealphaproject.eu/index.php?action=show_creature&id=4347
https://db.thealphaproject.eu/index.php?action=show_creature&id=4348
Should be located somewhere around Stonetalon Mountains, probably Cragpool Lake
https://db.thealphaproject.eu/index.php?action=show_creature&id=4085
They have full loot table and models. They should likely also be around Cragpool Lake.
https://db.thealphaproject.eu/index.php?action=show_creature&id=3993
This NPC is definetly related to Ilkrud Magthrull (3664), maybe it should be spawned along side him, not sure. My guess it's his pet/demon.
Wowhead comments say... "Has a Succubus minion pre-summoned before the fight, and once his health has been reduced to 50% or so, summons TWO Voidwalkers, as well as constantly firing Shadow Bolts at you.", so I believe this Doomguard is what he uses in this version instead of succubus, pre spawned.
https://db.thealphaproject.eu/index.php?action=show_creature&id=3878
Pretty sure this mob should be in the water in Ashenvale, near Zorams Strand.
https://db.thealphaproject.eu/index.php?action=show_creature&id=3722
Rare in The Barrens
https://db.thealphaproject.eu/index.php?action=show_creature&id=3652
These are invisible ghosts outside Undercity.
"Lordaeron Citizens are invisible wraiths found in the Ruins of Lordaeron of Undercity. They can only be seen by various methods of detecting invisibility, such as the warlock spell [Detect Invisibility] or the mage spell [Invisibility]."
https://db.thealphaproject.eu/index.php?action=show_creature&id=3617
I mean his ID is in the correct range. He is originally in Stormwind water, although I cannot say for sure he was there in 0.5.3 - his ID could have been something else back then, who knows.
https://db.thealphaproject.eu/index.php?action=show_creature&id=3581
Missing Stormwind child, he should patrol around with the other kids in Stormwind. Pretty sure that they follow Christina
https://db.thealphaproject.eu/index.php?action=show_creature&id=3509
Should wander around in Wailing Caverns, maybe even the Barrens, I am not completely sure.
https://db.thealphaproject.eu/index.php?action=show_creature&id=3680
A dragon who should fly around in Blasted Lands.
https://db.thealphaproject.eu/index.php?action=show_creature&id=2757
Another dragon, a twin of Blacklash. Also flying around in Blasted Lands.
https://db.thealphaproject.eu/index.php?action=show_creature&id=2759
A weapon trainer in Orgrimmar. Unsure of exact location, but in vanilla he is in The Valley of Honor.
https://db.thealphaproject.eu/index.php?action=show_creature&id=2704
Quest mob in Stranglethorn Vale. In vanilla, he is in a small island to the north. Quest says:
"... I have heard about a sunken troll city out near that island you're looking for. Maybe you should try there.
Destroy the Altar of the Tides with Catelyn's Blade, kill Gazban and bring the Stone of the Tides and Catelyn's Blade back to Baron Revilgaz."
https://db.thealphaproject.eu/index.php?action=show_creature&id=2624
Gazban also has two interesting related spells which turn him into a water elemental:

I believe he should wander around the island with the lesser water elementals (ID 691), around:

These mobs are part of a scripted event, where they (I think 6 of them) will be stealthed behind the magistrate building in Southshore.
"This is a timed/scripted event, it starts with the Southshore Crier running into Southshore (form Tarren's Mill direction) and yelling: "Help me! Help! Assassins in the Hills! To arms! To arms!"
Then Southshore Guard says: "Go to your posts! Let no invader reach Southshore!" and "Anyone suspicous is to be taken down quickly. Get to your posts as quickly as possible" Even if you miss this part with all the yelling, you can still figure out if the Assassins are about if you just take a look a the guards. While this event is active, almost all guards around Southshore are doubled, so if you see many more than usual guards patrolling, then the assassins are near. They try to sneak into Southshore and some are just waiting around SS."
https://db.thealphaproject.eu/index.php?action=show_creature&id=2434
Part of the same scripted event as number 26 above. This scripted event is probably missing.
https://db.thealphaproject.eu/index.php?action=show_creature&id=2435
These guys should probably be at the most north of Darkshore, in the water.
https://db.thealphaproject.eu/index.php?action=show_creature&id=2188

https://db.thealphaproject.eu/index.php?action=show_creature&id=1800

From Beta Journals 2004:

My best bet would be at the top of the mage tower in Hearthglenn (Western Plaguelands), probably at:

Already posted about Stitches here: #1611)
"Watcher Corwin will spawn if Stitches gets near the town"
https://db.thealphaproject.eu/index.php?action=show_creature&id=1204
https://wowpedia.fandom.com/wiki/Watcher_Corwin
Wasn't added to the game until: Patch 1.3.0 (2005-03-07), his ID was probably used for something else in 0.5.3
Action needed:
Currently under ground in Silithus, should be removed from the game.
NPC or NPC ID might be reused in the future.
https://db.thealphaproject.eu/index.php?action=show_creature&id=1233
An alchemist in Ironforge. "Until patch 2.3, he was an journeyman alchemy trainer." unknown exact location - near gnome "tinker town" perhaps?
https://db.thealphaproject.eu/index.php?action=show_creature&id=1246
In vanilla he is in Desolace, but all nearby IDs before and after him is in Stormwind.
I would guess that in 0.5.3, he is somewhere in Stormwind. Needs further evidence I guess.
However, the items he sell is in the correct level range to Desolace. Also, Desolace has 2 other NPCs in 0.5.3 at the moment (not sure if that's their correct location, though).
https://db.thealphaproject.eu/index.php?action=show_creature&id=1322
This guy should be located in Stranglethorn Vale. Also missing a model.
https://db.thealphaproject.eu/index.php?action=show_creature&id=815
This mob should be in Stonetalon Mountains.
https://db.thealphaproject.eu/?action=show_creature&id=4002
In beta this mob is in Andorhal, as can be seen in the combat log here:
https://db.thealphaproject.eu/index.php?action=show_creature&id=4476
According to this map from patch 0.6, there is supposed to be a Crawler Trainer near Prospector Remtravel.
https://web.archive.org/web/20040619170636/http://wow.warcry.com/content/atlas/darkshore.php
The map is broken, but in the page source we can read this:
<area shape="circle" coords="358,550,10" href="#" onmouseover="ddrivetip('<b>Remtravels Excavation</b><br>Prospector Remtravel<br><br>Crawler Trainer', '', 200)" ; onmouseout="hideddrivetip()">"
Meaning these two mobs, "Prospector Remtravel" and "Crawler Trainer" are near eachother. This map on warcry does not show NPC names for pet trainers, unfortunately.
I think it could be either Jadenvis Seawatcher or the World Crawler Trainer, since both are night elves and would fit Darkshore.
Having a Crawler Trainer in Darkshore also makes sense, since the shoreline is filled with crabs.
- [ ] 43. Skinner and Leatherworker at Faol's Rest
According to this map from patch 0.6, there are two NPCs at Faol's Rest:
https://crawler.thealphaproject.eu/mnt/crawler/media/Website/warcry.com/Atlas-May-June-2004/WoW%20Warcry%20-%20Content%20-%20Atlas%20-%20Tirisfal.php.html
Needs investigation, I suppose.
"Mobs found in Faol's Rest
Rand Rhobart Undead 13 Tirisfal Glades
Shelene Rhobart Undead 12 Tirisfal Glades "
However, Rand Rhobart is ID 6289, which are not present in 0.5.3, so Shelene Rhobarts location right now is probably correct for 0.5.3.
According to this map from june 2004, patch 0.6, Harl Cutter is supposed to be spawned at Sentinel Hill in Westfall:
https://crawler.thealphaproject.eu/mnt/crawler/media/Website/warcry.com/Atlas-May-June-2004/WoW%20Warcry%20-%20Content%20-%20Atlas%20-%20Westfall.php.html
So it is very likely he was there in 0.5.3 as well, probably close to the lumberjacks.
https://db.thealphaproject.eu/?action=show_creature&id=841
Prior to patch 1.11.2, this mob was located in Tanaris.
https://db.thealphaproject.eu/?action=show_creature&id=5432
Not sure when this mob was removed or added, but the NPC ID matches in 0.5.3, and this mob was removed during the beta.
A mob in Thousand Needles, according to this archived mob list:

Not sure if this "script" is in or not, but:
Defias Ambushers are human bandits that may appear when Clara Charles visits the well near her house in Elwynn Forest, just south of Stormwind City.
Well actually, Clara Charles (5917) is not in the DB. So maybe the Defias Ambusher was used somewhere else in 0.5.3.
According to this list from 15-04-2004 https://crawler.thealphaproject.eu/mnt/crawler/media/Database/WoWPython/wowpyton-15-04-2004-creatures-spawn.txt
, Defias Ambusher is supposed to be at location -9192.6 310.04 77.9829 0.

Charred Stone Spirits were earth elementals that were found at the Charred Vale in Stonetalon Mountains during the original beta

Some more beta-removed mobs that are still present in the database, but do not appear in the crawler (excluding unreleased mobs):

Removed NPCs (click here to show list)
Goli Krumn (ID 1365) was removed from this list, because he wasn't added in the game until the "Winter Veil" event, which wasn't added to the game until Patch 1.2.0 (2004-12-18). So this NPC either got repurposed, or replaced another NPC with this ID.
Link: https://db.thealphaproject.eu/index.php?action=show_creature&id=1365
There's probably many more, from the link below, and those which IDs have been replaced or reused.
But these are the ones of interest that I have found so far.

Prior to patch 1.11.2, this mob was located in Tanaris.

Not sure when this mob was removed or added, but the NPC ID matches in 0.5.3, and this mob was removed during the beta.
A mob in Thousand Needles, according to this archived mob list:

Not sure if this "script" is in or not, but:
Defias Ambushers are human bandits that may appear when Clara Charles visits the well near her house in Elwynn Forest, just south of Stormwind City.
Well actually, Clara Charles (5917) is not in the DB. So maybe the Defias Ambusher was used somewhere else in 0.5.3.
According to this list from 15-04-2004 https://crawler.thealphaproject.eu/mnt/crawler/media/Database/WoWPython/wowpyton-15-04-2004-creatures-spawn.txt
, Defias Ambusher is supposed to be at location -9192.6 310.04 77.9829 0.

Charred Stone Spirits were earth elementals that were found at the Charred Vale in Stonetalon Mountains during the original beta
Seems to be level 22-23 or level 25-26 depending on the sources...
A level 39-40 demon in Desolace:

Should be in The Barrens, level 22-23, at least in beta patch 0.9, 2004-08-19. Since this mobs ID matches 0.5.3, I'd bet it was in game here too.

Some more beta-removed mobs that are still present in the database, but do not appear in the crawler (excluding unreleased mobs):
Removed NPCs (click here to show list)
Goli Krumn (ID 1365) was removed from this list, because he wasn't added in the game until the "Winter Veil" event, which wasn't added to the game until Patch 1.2.0 (2004-12-18). So this NPC either got repurposed, or replaced another NPC with this ID.

There's probably many more, from the link below, and those which IDs have been replaced or reused.
But these are the ones of interest that I have found so far.
