That’s a tough one, but I’d probably have to say the girallons. Nothing more terrifying than a 4 armed ape that can literally rip party members in half if they get a good grip. We had one encounter where just a couple of the things really beat the snot out of our party. It wasn’t fun.

Second …

As far as a specific dragon goes, the hands down winner is Tiamat/Takhisis. This is probably due to my great love for the Dragonlance books & modules as well as the Dungeons and Dragons cartoon that I watched as a kid. And yes I know she’s a deity and not strictly a dragon, but I don’t care.

As …

Fey annoy the crap out of me. Stupid tree-huggers. :)

Of these, my favorites are the fire giants. Tough, smart and not taking any crap from anyone. This goes back to the original 1st ed. G-series modules “Against the Giants” (G1, G2, G3). These were fantastic modules that ended in the “Hall of the …

Next up is Thelisn. I wanted to play a character who was completely different from any others I’d played to that point. One class I’d never played before was a rogue. Enter Thelisn.

Love the shield guardians. Delban had one for a while and it came in quite handy for saving his life multiple times. I also am fascinated by the more unusual golems. For instance, in 3e there was a stained glass golem that was pretty cool and Pathfinder has added a few like crystal golems and …

This covers a wide band of creatures, so it’s hard to pick. I mean you’ve got celestials, formians, demons, devils, eladrin, djinni, mephits, nightmares, tieflings, slaads, and many, many more. How can anyone pick from among those? Let’s just pick one at random and say hell-hound. Here, doggy, …

Driders…. Always driders. I love and hate those bastards. Yeah, I know, they’re not an animal or insect or technically an arachnid, but close enough for me. Though, when we ran through City of the Spider Queen we did run into a massive spider or two that made for some fun combats. Still, though… …

Oh, another tough one. It’s a toss-up between beholders and illithid. They are both a lot of fun from a game stand point. And by fun I mean “AH! AH! AH! AH! RUN! RUN! RUN! RUN!”. Seriously though, one of the most fun adventures we have run was the Illithiad modules.

Although, the party did have a …

Bodaks. When one of my characters died by a bodak’s gaze and then turned into a PC bodak for a time, it was a lot of fun. Short lived, but fun. Unfortunately, as an undead, there was no way for the party to heal my wounds and eventually the damage accrued to the point of my destruction.
