I've got an idea for a series of possum Pokemon.
Oposease (O-pa-cease)
Species: Feign
Type: Normal
Name's Origin: Oposease is a combination of 'opossum' and 'decease,' a good combination considering how this is supposed to be an opossum that looks like its been dead for a while.
Description: Overall, Oposease is a dead opossum (kinda…it's really still alive, but just looks like its not supposed to be). Its pale brown skin is tight against its body as if it's not eaten anything in a long time, so bones, like its ribs, the vertebrae of the backbone, and the pelvis are kind of visible. The legs and arms are kind of scrawny. The half of the lower jaw hangs downward because it's supposed to be broken. Finally, the irises are small.
Gender Differences: Males have part of their right ear bitten off. Females have a small, but somewhat noticeable slit on the front part of their lower stomach/pelvic area (kind of a pouch for babies, like their real-life counterparts are supposed to have).
Gender Ratio: 50% Male/50% Female
Height: 1' 10"
Weight: 12 lbs
Ability: Stench/Bioboost-A special chemical circulates through the Pokémon's body when it's under attack to raise its Attack and Defense power.
Pokédex Entry: Oposease's appearance and foul odor convinces many that it is born dead. Scientists have determined that this façade is a perfect defense against predators that only eat prey when it's fresh.
Evolution Line: Oposease can evolve into Oposombie starting at level 22 and when it's become somewhat friendly with its trainer. It then can evolve into Oposeteer if it's holding a Play Stage, it's become somewhat hateful of its trainer, and it doesn't know the move Play Dead.
Oposombie (O-poss-om-bie)
Species: Decaying
Types: Normal/Ghost
Name's Origin: Oposombie is a combination of 'opossum' and 'zombie,' kind of following the ideas behind Oposease, but this time it's actually died and come back as a zombie. Also, like a zombie, Oposombie is supposed to be a servant Pokémon.
Description: Oposombie is basically a larger version of Oposease. The only true aesthetic differences are how the left ear and large portion of its head behind the left eye that extends to the back of the head is missing, revealing a gray colored area of tissue, the vertebrae of the spine stick out somewhat from the skin, and the tail is all bone.
Gender Differences: The same as Oposease. The males have a part of the top of their right ears bitten off, while females have a small opening where their pouches are.
Height: 2' 10"
Weight: 24 lbs
Ability: Zombie Walk-Attack/Special Attack moves can't harm Oposombie (that is, it's still susceptible to status problems like Poison and Burn conditions). Also, this ability can't be suppressed by moves like Gastro Acid or the Mold Breaker ability.
Pokédex Entry: Oposease has a short lifespan, dying 22 weeks after birth. However, folklore speaks of how one who has formed a tight bond with one discovers that it returns to him or her as Oposombie.
Oposeteer (O-pos-eh-tear)
Species: Theatre
Types: Normal/Ghost
Name's Origin: Oposeteer is a combination of 'opossum' and 'puppeteer.' Unlike Oposombie who was a servant, Oposeteer is a reclusive creature whose sensitivity to its trainer's fear and/or mistreatment of it as well as the curse on a toy it was given to keep it occupied while its owner was elsewhere caused it's mind and body to develop to reflect its frustration and give it the ability to control others.
Description: Oposeteer retains some of the same characteristics that Oposombie had: the head with a part of the left side missing, scrawny arms and legs, and the bone tail. The major difference between the two, however, is that the torso and abdomen have been replaced by a miniature theatre stage with red curtains that cover up the back parts of the stage. Oposeteer's ribs reach around from the back of the theatre and grab onto the sides of the stage. It's spine stick part way out of the backside of the stage, enough to show that the stage is part of the creature. Finally, the arms rest on the top of the stage and puppet strings drop down from the tips of Oposeteer's claws.
Gender Differences: The male still has part of its ear missing. The female has no specific characteristics.
Height: 3' 10"
Weight: 86 lbs
Ability: Possession-When Oposeteer is on the field, all other Pokémon are only allowed to use one move until they switch out or faint.
Pokédex Entry: The fear and hatred that its trainer had for it as Oposombie caused Oposeteer to become obsessed with showing its aggressions in the way it knows best, by taking control of those who despise it and forcing them to perform in its plays.
Okay, I probably didn't have to put pronounciations after the names, but it's probably easier to figure it out that way.
Here are some attacks that are unique to them.
Play Dead-By making itself appear to perish the first turn, Oposease or Oposombie allow themselves to be struck by a physical attack without taking damage and then unleash a savage clawing attack that is sure to strike the next. Type: Ghost Category: Physical Power: 90
Puppet Pawn-By attaching its strings to an enemy, Oposeteer can force it take any attacks, except for physical ones that it launched, instead of Oposeteer. Type: Ghost Category: Other
