Princess of the Universe

Watermarked PDF

Get ready for action figure fantasy in the tradition of She-Ra and He-Man!


Here you stand, bearing arms in the name of Virtue against the arrayed villains of the distant planet Eidolon.

You have great powers, and great responsibilities, and you are entirely up to the challenge of both.

The challenge to be...


Experience action figure fantasy the way you always wanted.

Epic Heroism.

Snake Queens.

Queer Inclusion.

Warrior Bears.

Time to be part of the greatest franchise that never was!


Princess of the Universe includes the setting of Eidolon. We describe Eidolon both during the Curse Age (the battles between Valoria, Princess of Courage and her nemesis Evil Eye, Wicked Witch of Wisdom) and the Hope Generation (where your heroes become the Champions of Virtue to defend Eidolon against past and future threats)!

Play a snake queen from Ophidia Pax! A robot from Automata Infinita! Or even a toughened survivor of the Blighted Lands!


Princess of the Universe uses a brand-new (but extensively playtested) system to deliver all of the action you'd expect from playing with your favorite toys. Build an action-figure-worthy protagonist with risky, core, and apex powers, using them to build bigger dice pools and determine the consequences of your actions. Create anything from a Heroic Battle Bear to an Evil Reptilian Time Rebel.

And remember how the highlight of old cartoons was the villains and their dysfunctional banter? You'll make both heroes and villains, while the Game Master takes control of the archvillain, in charge of coming up with vile schemes for her henchmen to carry out and the heroes to thwart!

Yes, the GM gets to do the Skeletor voice.

Despite purchasing this on DriveThruRPG, the website is not allowing me to leave a review. So here it is.

Princess of the Universe attempts to capitalize on the nostalgia of the She-Ra: Princess of Power setting while erasing all of the serial numbers. While I am not adverse to the concept -- in fact, I was hoping to find a fun product -- I was severely disappointed with Princess of the Universe.

Of the 52 pages in the pdf, 12 of them are blank. Other than the cover, there is no art in the entire product. The print is large... unnecessarily large. This pdf could be half its size, if it used a normal-sized font.

Descriptions of the characters -- both heroes and villains -- are less than bare-bones. Setting material is actually quite good, and includes a decent history for the world; but certainly leaves one wanting more.

Mechanics for the original system presented in the pdf are practically non-existent.

I feel like I paid $7 for what should have...See more

For what it's worth, the listing only says it's 44 pages. Personally, I like concise materials and simple rules as long as they get the job done. Although $9 does sound a bit steep for this amount of content, especially sans art. If it's good material, this sounds more like something I'd pay about 4-5 dollars for. The preview doesn't really give you a good idea of the game, so there's nothing here to counter your arguments.

Wanted to see the preview but it doesn't want to load. Is there a preview on the publisher site?

I'll have to consult with DriveThruRPG on what's wrong with the preview, but here are previews from my blog (it's Patreon, but the previews are public and free):

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
