Ok! :P
And I've never heard of a 1980 drama called Berzerk! - any details?
Something massive with a stomp attack = slows player down when nearby.
Using Adrals template (I assume Dexterity's more of a hit rate/attack speed?) I'd say,
Name: Behemoth
Strength: superb
Dexterity: good
Speed: poor
Attack type: melee
Special abilities: ^, and possibly an "ability" preventing knocking the player back (simulating a downward smash or bite attack)
Behaviour: simple track-the-dot - goes right for you. He's too slow for games and too strong to hold back. Obviously, terrain won't be a problem.

Name: Shrieker
Strength: fair
Dexterity: great
Speed: great
Attack: melee
Special abilities: invisible more than a tile away, but shrieks are heard. Possibly has an unnerving effect (no ranged attacks, high miss rate) when not berserking. Regeneration?
Behaviour: violent straight-forward attack, suddenly retreats after a few hits and attacks from another direction. If made weaker it could attack in bands, for a very confusing effect considering you wouldn't know when you're done with them.

Name: Swolen
Strength: good
Dexterity: fair
Speed: poor
Attack type: melee
Special abilities: cannon fodder! Stronger and slower than beasts. Maybe stench for a slight energy drain when near.
Behaviour: simple.

Name: Sporewhore
Inspired by the Starcraft Queen and a casual Succubus, I'm not sure what to make of it, only that it will have "minions" attacking and retreating, yeah, like a SC Carrier :) . Seems more like a DC-comics villain name than a good monster race, though, so maybe it should be a sarcastic boss' nick.

I suggest only Kornel looks at this one, in case it's included.
I also suggest it is edited out by him if that might happen.
Name: Unearthly Veil
Strength: see below
Dexterity: Legendary
Speed: see below
Think of it as a swirling mass of ghost-like lights, all of the purest white.
Despite this it has a corporeal core, and is affected by solid blows, though mistaking the aura for it's body for it may lead to thinking otherwise.
It burns with intense heat, however, and reaching that core is another matter, as there damage per round is very high. Ranged weapons are likely to burn before they hit the center, and fire's simply pointless to use against it.
Monsters immune to heat are shielded, therefore, within it's outer form, and often travle with it - the blinding effect of the UV causing many to mistake additional blows for scything flames within the light.
Since much "movement" is lost on the spinning effect of the lights, movment rate is relatively low, but they spin very fast, and have a very misguiding dodge rate ;)
Attack type: special burn effect depending on distance. Auto-hit.
Special abilities: aside from those described above, the UV masks terrain and creatures gradually as it nears the core - the color becomes whiter but recognizable by look and 'l'ook, but after a certain line, just white.
Behaviour: very "regal" and uncasual, possibly never really moving towards the char except to keep him inside some of the burn radius.
