What follows has been, for the past few weeks, a labor of love. It grew out of a desire to have a sortable list of Gamma World monsters, as well as a consolidated place for me to find the right monster for every encounter in one place. In the process, I learned a lot about Gamma World monsters, and got a real feel for the game and the challenges presented by it. This little project took a bit longer than I expected, though there was also a bit more to it than I’m presenting here – more on that next week. For now, an introduction to the Gamma World monster index:
Every creature has one of three* Origins, which are mentioned in the Gamma World core book (p. 102), but aren’t detailed too much. I’ve added some details based upon my observations in putting the index together.
(*There is a “fourth” origin. The Forestal from the LoG expansion has the “Natural” origin. Since this is the only creature with such an origin, I’ve assumed it was an editing oversight, and changed it to “Terrestrial.”)
- Terrestrial – This is the easiest one. These are monsters you’d “normally” find on earth. Most plants, insects, and robots fit into this category, as do the “animal” humanoids (badders, porkers, hoops, etc.)
- Extradimensional – This is a difficult one, and only a few creatures are actually in this category. Demons are an obvious example. There are also some “weird” humanoids that also fit into this category – Sleeth (psionic lizardfolk) and Serfs, supposedly because they come from another dimension. The famous Yexil is also in this category. If you’re porting D&D monsters into your Gamma World campaign, I’d probably put Aberrant creatures in this category, along with elementals, and (obviously) demons/devils.
- Extraterrestrial – The origins are more about where the creature is from than about what it looks like. That’s why I said Extradimensional is difficult – many of the monsters in the Extraterrestrial category seem like they should be Extradimensional, but they’re not. Klard Nar (LoG) is a good example (and a construct? Really? Hmmm…). In this category, you have your usual suspects like aliens (“visitors”) as well as some head scratchers, like the Maneater, which is a giant plant monster (thought that one would be Terrestrial).
There are also three Types of creatures from each origin, the details of which can be found on page 102 of the core Gamma World book.
All creatures have some combination of the above. Some creatures also have Subtypes. Some of the more common subtypes are robot, plant, and insect. A few subtypes only come up a couple of times (blind, ooze, construct).
You will notice that some of the information on the spreadsheet is in bold italics. This is information that I changed from or added to the original monster’s information. Why did I change information? As I went along, there were a few mistakes I noticed, as well as omissions that I couldn’t let pass. Take Gren, for example. In the core rulebook, Gren are Extradimensional Humanoids. However, in the Legion of Gold expansion, they are Terrestrial Humanoids. I had to reconcile that.
I also changed a few categories based upon what I could infer about origins. The most clear example of this would be Haunts (ghosts). The Haunt Astronaut was originally Extraterrestrial, and the Gamma Ray Haunt was Terrestrial. I changed both to Extradimensional.
Much of what is in bold italics were additions – many of the insect creatures didn’t have the insect subtype, for example (Tiger Beetles don’t have the insect subtype? Or Giant Wasps? Really??).
I did remove two subtypes – In Famine in Far-Go, p. 123, two of the Porkers listed have the “porker” subtype. I struck this because, like the Forestal’s “Natural” origin, I assumed it was an editorial oversight. I also struck the Tar Horror’s “aquatic” subtype. Even though it does have a swim speed, I just don’t think of oozes as “aquatic.” Feel free to add that one back in.
Finally, I added a new subtype keyword – Mount – based upon seeing rules for it in some of the stat blocks. If you’re looking for a creature that your PCs can capture and use as a mount (or a mount for your monsters), look for this keyword. This is especially important for PCs with the Beast Rider Vocation. That’s not to say that other monsters wouldn’t make good or fun mounts (Latterbugs, Modos, and Yexils come immediately to mind), but their stat blocks do not include rules for when they’re mounted, so technically they can’t be mounts (LoG p. 21).
