Friday Creature Feature: Malicious Marauding Pyramid Heads

Sometimes I feel like being original and creative, sometimes I feel like converting one of my old monsters, and sometimes I just feel like ripping off one of Tom's (literally) pulp villains.  Guess what this is.

MALICIOUS MARAUDING PYRAMID-HEADS Medium Aberration Hit Dice: 8d8 Speed: 30 ft Armor Class: 17 (natural) Attack Bonus: +7 melee, +6 ranged Damage: by weapon Special Qualities: Damage Reduction 10/Fire Saves:  Fort +2, Ref +2, Will +6 Abilities: Str 13, Dex 11, Con 15, Int 10, Wis 14, Cha 9 Environment: any These alien marauders travel the multiverse stealing and assimilating technology from other races. They are particularly keen on time travel technology. Pyramid heads are utterly ruthless towards other races, having no regard for anyone but their own kind. When encountered, pyramid heads are likely to have an eclectic assortment of weapons and devices collected over the course of their nefarious careers. The pyramid heads are seven feet tall and bipedal with pyramid-shaped heads and four-digit hands and feet. They appear to be evolved from some kind of sentient ooze, as their flesh has a jelly-like uniformity and is highly resistant to conventional attacks. Kazap Pistol: Damage 1d6, plus knocks target back 2 feet per point of damage. They also must make a Reflex save with Difficulty equal to the number of feet thrown back plus 10 in order to avoid falling prone.)
