Diamoaka

Diamoaka (pronounced Die-uh-mo-ah-ka) is the result of an offspring from a non-pangwi and pangwi species. the term comes from Zepalugada roots literally meaning "Dia" = "bad" + "moaka" = "mix". By pangwi law it is forbidden for pangwi to have sexual relations with non-pangwi species for this particular reason.

What's so bad about diamoakas?
Pangwi's bodies are designed specifically to cage and control the ridiculous reservoir of energy within them. Mix that DNA with a specie not designed for that and it can lead to some catastrophic disasters. Often, if the non-pangwi species is the host, this developed energy will often end up consuming or exploding the host and the host's surrounding area because, it's like they're trying to host a mini sun or black hole inside them. They literally become a ticking time bomb. If a pangwi was the host the offspring might survive being born but will have very little control of that energy from the pangwi-side of themselves. This may result in the diamoaka being killed from their own energy, similar to how a non-pangwi host might succumb to, or be unable to control their own energy becoming a danger to others around them.

There have only been a few cases of this in history. Almost all cases resulted in black holes or little sun-like explosions... it's probably an appropriate rule set by the pangwi government. There is one diamoaka known to survive, because they did not develop the amount of energy equivalent to that of a pangwi. Not much is known about them for the moment.
