((Here's a list of as many Nether-creatures I can think of. I'll continue to add to the list all the time.))
Netherstalker- A giant spider, depending on it's number of eyestalks, you can tell it's rank.
Mimic- Mimics, depending on their rank, can change into any form, as long as the subject is near. Higher leveled mimics, say, Rank 4, can change into adult humans. When you are asleep, the lick the sweat off of you. (I know it's gross, but that's what they eat.)
Dangeroo- These nethercreatures look alot like kangeroos, but are ten times worse. They can jump over 50 feet high, and their kicks are 10 times worse. If you are taken by one and placed in tis pouch, then beware. The top will instantly seal, and the dangeroo will wait until you sufficate, then procede to eat you.
Gremlin- These nethercreatures are no threat to you in the Nether- jsut an annoyance. They love electronic things, they eat the wires and electricity that is inside of it. They can cause real problems if let loose on Earth.
Hags- The hags reside somewhere in the 3rd Ring. They are all females, who look terrible, smell worse, and have terrible patience. Their wings are leathery, and their queen is the worst of them all. They eat your memories, and eat them like candies. Once they eat one, you cannot ever get it back, without a trade. You may give them a memory, though, and get a chance to go into their maze- the maze of gorgons. If you reach the end, you get a Shadow. This shadow points to the thing/things/person/people you love the most.
Gorgons- These creatures, if made eyecontact with, turn you into marble instantly. You may only be turned back if the gorgon who turned you itno marble is caught, and their head it cut off.
Netherbats- These giant bats are quite dangerous, but their fatal flaw- flour. You toss it onto their eyes, and, blam! They can't see, and, and virtually helpless.
Goblins- Mainly found in the Outer Ring, Goblins are alot like Gremlins, except these nethercreatures can grow up to rank 3's.
(Nether Versions of Scorpions)- These creatures are quite hard to kill, they can have up to three stingers, and have a voice that could kill. Literally. When they sing their highpitched, tuneless song, on teh last note, your head will explode.
Hydra- Hydras are creatures who live in the 3rd/4th ring, (in the ocean like areas) serpeant like things. They have four heads, and all of them are male except for one. The queen. The queen has many babies, (all male, usually) and they grow up, with their sole purpose to protect her.
Netherstingers- Netherstingers are like giant versions of jellyfish. They live mainly in the 3rd/4th ring, in the ocean like areas. They all come together when one is attacking anouther creature. They have a defense mechinism, which is to explode. They are like bees- the safety and well being of the hive/herd/clan is more important that their lives. They explode around the creature until it is dead, and the jellies take it back to their cave/hive/nest.
