Heyas, though I hate to do say it, you'll have to use another creature. I specifically state it needs to be an original creature. A creature not only from mythology, but directly using its abilities can't qualify as original.My entry is heavily researched and drawn from Hindu mythology. This has to be one of my favorite undead of all time, so check out the Vetala!
I mean, you could do something like a Terra Cotta warrior, or however you pronounce it, as you'd be making it all up from a concept that doesn't go into specifics, but just putting stats to an already long-developed creature won't work.
Also, even though it comes from an indian theme, the requirement is still that all entries have to have a haiku to be complete.
As long as they are all the same species, feel free.
