It's an interesting idea, that if you want to use psionics in your game, every creature might become psionically active. Or at least, have the chance to, just as some sentients will be but most will not.

So, if that takes your fancy, here are a whole bunch of well-known familiar monsters retooled to have psionic abilities as well as teeth and claws and whatever. The neat thing is, they are not just the monster you already know with psionics tacked on, read through the descriptive text and you will find that they have become quite different creatures, subtly twisted to become something else entirely. Use the original non-psionic version as well and really catch the party out!

There's a quick psionic primer, but if you are not familiar with the underlying concepts you may be a bit lost: Read 'Psionics Unleashed' by Dreamscarred Press to get the full picture.

A lot of the monsters are evil, and those who are not are generally neutral, like the Cat Psionic (thought all cats were a bit that way inclined anyway) or the Crystal Eater, a remote cousin of a Rust Monster which scoffs crystal rather than ruins metal. The Golden-Eyed Owlbear is more intelligent than the mundane version, unfortunately it may be smarter but it is no less vicious and bad-tempered. And as for the Red... it is a psionic hobgoblin, and a really nasty piece of work.

Each creature comes with a picture as well as full stat block and descriptive text. The picture of the Golden-Eyed Owlbear is particularly beautiful, with fur and feathers blending in a realistic manner.

An appendix contains psionic feats and powers for those wanting to explore some new ones. Plenty of scope for confusing, dominating or plain scaring your enemies there.

Overall a nice collection that is plausible within the context of psionics having developed within your campaign world, rather than having arrived from elsewhere. Well worth considering if you want to run a campaign that includes psionics as something that is around, generally available, embedded within the fabric of your alternate reality rather than an alien force imported in to it.
