It only leads to a loss of suspension of disbelief if you actually tell your PCs that they're fighting a Two-Headed Fiendish Anarchic Dire Owlbear. If you tell them that they see a looming red-skinned two headed creature that resembles a cross between an owlbear and something from their darkest nightmares, then you got yourself a serious encounter on your hands! Really, reading some of these combinations is worse than the image that such a creature would actually have.
Or perhaps my half-fiend (descended from a myrmyxicus) vampiric ixitxachitl... The vampyrmyrmyxitxachitl
The PC roster in my current campaign includes:
1. A tiefling mermaid - her mermaid traits coming from a bond with an artifact not unlike Ariel's "voice shell" in "The Little Mermaid".
2. A hagtouched oceanid - daughter of a salt hag and triton. Salt hags are the daughters of night hags and sea elves. Hagtouched is a template of my own design, to describe the descendants of my half-hags.
3. A Sea Haggle - a fine damselfish hivemind (swarm, aquatic) formed from a hag's eye talisman when it's covey is simultaneously destroyed.
4. A modified human - Altered with fish hag grafts. A fish hag is a pseudonatural hag, the original shellycoats, now extinct on Oerth.
5. A half-dragon (topaz) succubus - technically she is a half-fiend/half-dragon, but I am attempting to see how it goes, playing by the rules for a change and using the succubus levels in Savage Species. I did add the ability for the half-topaz to breath underwater, as the OA half-dragons can do in Draconomicon.
6. A triton prince - half-brother to the oceanid.
So, what's the problem slapping a few templates onto their opponents?
