THIS IS ONLY ONE HALF OF THE SCYTHOD. I was just trying to draw a quick schematic so Mr Frog would know (very roughly) what they look like.
They're loosely designed after the praying mantis.
They're capable of slicing things up with their scythe arms (unprotected hands and feet are especially vulnerable), and the claw at the end (not really tentacles, but I have no idea what to call it - I haven't seen anything like it in real life before) is capable of literally stabbing
into an enemy's body, and opening up
inside their body cavity. Following this they can shake their foe around and cause massive internal damage. Their spike legs are good for stomp-stabbing enemies (and spearing them, too, apparently). Their claw arm isn't good for much besides scratching and holding weapons. Their teeth, however... A triple set of snake dentaries (I may be spelling that wrong, but I basically mean one half of a snake's lower jaw) rings their mouth, and they can easily latch on or rip somebody to pieces. Their bites are usually deadly just from the force behind it.
Mr Frog and I collaborated on it a while and decided that they're from a planet far away, largely volcanic with a dense co
2 atmosphere. It's in orbit around a brown dwarf, thus no light. As a result, they don't need eyes. However, they have a very well-developed sense of smell and hearing. Their spikelegs (hella sharp) are useful for climbing among the rocks. Due to the scarcity of what we would call "plant life" they focus their lives solely on being predators. Although intelligent, they're not incredibly so, forming tribes and such. In the original Frogmod, they were going to be taken to Dwarfworld by the Seqiv, who had space travel. Now... who can say. They were designed to be the brute force side of the aliens - the seqiv being intelligence and stealth.
edit: their language sounds like a series of clicks and hisses. But for writing purposes... first 25 words of their language file:
