There are many, many critters that you will see in Fallout. They range from rats to super mutants to Deathclaws. This is an incomplete list, as there is quite a large number of creatures in the game.

[edit] Rats

Rats are relatively easy creatures that you will see in the beginning of the game.

Name	HP	xp	Weapon	Armor	Notes
Cave Rat	6	25	Teeth	Fur	Instant death (to the rat) with strong critical.
Pig Rat	10	50	teeth	skin	Instant death (to the rat) with strong critical.
Lesser Mole Rat	22-26	65	teeth	fur	Instant death (to the rat) with strong critical.
Greater Mole Rat	26-30	120	teeth	fur	Instant death (to the rat) with strong critical.

[edit] Radscorpions

Radscorpions are closely related to the North American Emperor Scorpion, and have been mutated by the war. The increased size makes them larger than humans, and the venom contained in their tails can be used to make an antidote.

Name	HP	xp	Weapon	Armor	Notes
Radscorpion	26	110	tail	carapace	poison attack

[edit] Humans

Range from varying (townsfolk) to medium (raiders, guards) to difficult (Brotherhood Guards) - note that they have no special. Experience earned is not dependent on the hit points and/or difficulty of the target.

Name	HP	xp	Weapon	Armor	Notes
Townsfolk	10 to 141		varies (one guy carries a Super Sledge at the Boneyard)	varies from none to combat armor
Raiders	12-35		Pistols, SMG's, various melee weapons	Leather Armor
Junktown City Guards	20-50		Pistols, rifles, shotguns, various melee weapons	Leather Armor
Hub City Guards	59 or 83		Combat Shotguns, Assault Rifles, unarmed/melee weapons	Combat Armor or Metal Armor
Brotherhood Guards	35-95		Miniguns, gatling lasers, assault rifles, one has a rocket launcher	Power Armor/Brotherhood Armor
COC Techs COC Priests, BOS Scribes and Elders	35-75		varies, none to small energy weapons or pistols	COC robes (BOS Scribes have bluish or dark purple robes)

[edit] FEV creatures & Ghouls

This is the direct result of what happens when a normal human is injected with the forced evolutionary virus. Extremely big and strong, Super Mutants make a formidable opponent. They are typically seen with floaters and centaurs, two creatures that the FEV can also spawn. (At least I think so...)

Tim Cain stated that ghouls were victims of radiation poisoning, not victims of the FEV virus on an IGN post. It turned out that the ghouls were former inhabitants of Vault 12 (where Necropolis is at). Vault 12's doors never functioned, therefore Ghouls are victims of radiation poisoning.

NOTE: I have found evidence that supports both approaches to how ghouls were formed: Either speak with Talius at the Boneyards or see what happened to the inhabitants of Vault 12.

The FEV was designed at the place now known as the Glow with hopes of creating a super soldier. The virus makes the humans stronger, but lowers intelligence and in its current state, makes them sterile.

Name	HP	xp	Weapon	Armor	Notes
Super Mutant	40-140	250-500	any big gun or large energy weapon (or unarmed)	green - very lightly armored black - somewhat armored (miniguns/SMG's don't work that well against them)
Ghoul	12-100		same as humans, except they cannot use big guns or large energy weapons.	none
Glowing Ghouls	36-60		same as humans, but I've only seen unarmed so far	none	They can radiate you! If you use the geiger counter, you'll see about 5 to 10 rems. (Estimate here)
Floaters	50-75		Some weird appendage that I have no knowledge of (it's reasonably powerful and can knock you over)	thick skin (like master)	I'm not sure, but they can poison you.
Centaurs	94-130		Teeth, virtually the same knocking-over capabilities of its "floating" brethren	thick skin, but not as thick as Floater skin.	Same as floaters (I think)

Note: You'll only see Centaurs and Floaters in random encounters or in the first level of the Cathedral.

[edit] Robots

Robots - in a post nuclear game. They are either found in the Glow or in the two mutant bases. Pulse grenades do the best job, but plasma grenades and energy weapons should also do the job.

Name	HP	xp	Weapon	Armor	Notes
Sentry Robots (tan)	40	175	Unarmed	Steel
Floating Eye Robots (red)	60	275	Unarmed	Steel
Sentry Robots (black) / Robobrains	80	300	Rifles or Shotguns	Strong Steel
Mr. Handy	113	400	Minigun	Strong Steel

[edit] Creatures of the wastes

Creatures that wander around the wasteland, and don't fit under a particular classification.

Name	HP	xp	Weapon	Armor	Notes
lesser deathclaw/ deathclaw spawn		I think 300			can be found in the wasteland when traveling with a caravan from the hub, easier to kill than a normal deathclaw
Deathclaw	225	1000	Claws	Thick skin (don't be fooled - very strong)	Deathclaws are very strong and deadly creatures. Fighting one by itself isn't too hard with decent small guns skill, but fighting many is difficult. If you give Ian the .223 Pistol and Tycho the Sniper Rifle, then the two make an excellent Deathclaw-killing squadron. They (deathclaws) have an insane amount of action points, so watch out!
Mantis	20 or 30		Appendages	Exoskeleton	Mantis are only found in random encounters outside.
Dogs	14		Teeth	Fur
