I took Bugbears gave them Brachiation and made them 'Ape-men' (align Neutral), they are the jungledwelling 'Sasquatch' of my campaign. These Apemen get a disease like Lycanthorpy that transforms them into 'Wendigo' (Dire Bugbears with Spd 50 and a Blur ability). APemen psions are the Beaver folk of Slaine legend...
I've modified gnomes (they are now 15 inches high)
I have a telepathic race called 'Oni' who are tall and thin with long purple, red or silver hair and long twisting horns, all Oni hide their true faces behind masks and they are said to be refugess from another dimension (the look is taken from Noh Opera costumes). Oni have the power to 'fold space' (teleportion) as such any item they own seems to suddenly appear in their hands whenever they want it (and as a swift* action). Mrs Halkum Private Secretary to Orbril the Gnome, Master of the Grand Circus Maximus was an Oni (though she spent most of her time disguised as a human)
(i*t was a free action but I changed it when swift actions were introduced)
