First! The official League of Legends lore--
There once was a Piltovian man named Corin Reveck who had a daughter named Orianna, whom he loved more than anything else in the world. Though Orianna had incredible talent for dancing, she was deeply fascinated by the champions of the League of Legends. This fascination compelled her to begin training to become such a champion. It is unfortunate that her sheltered, wide-eyed naivete led her to take unnecessary and dangerous chances which ultimately led to her tragic demise. Orianna's death shattered Corin, driving him into deep depression and an obsession with techmaturgy. He could not stand the void his daughter's death left in his life, so he decided to build a replacement – one that would complete Orianna's dream of joining the League. What was created is the clockwork killing machine that Corin named after his daughter. Knowing that she was destined to be a champion and seeing the way the times were changing, he created The Ball as her pet and protector. This nearly symbiotic creation uses a different type of techmaturgy, relying more heavily on electricity than clockwork.
Orianna and The Ball now fight as Champions in the League of Legends, using her sometimes misguided morality as a compass. She tries in earnest to fit in with those around her. However, no matter how hard she tries, Orianna can never be human and there is always something unnerving and alien about her. Though she attempts social interaction with other champions in the League of Legends, there are few who can get past her exotic nature. To many, it's as if there's nothing inside, that Orianna is just a soulless clockwork shell – a dangerous and deadly one at that. However, all along she remains a perfect daughter in her father's eyes.
And that's all the official lore.
Orianna was a bit... disoriented (if you think she's capable of that emotion) upon entering Nexus. After all, she was built solely with League of Legends in mind. But she found a few mechanics by sheer luck that were used to unusual technology. They added a few systems, intending to use her as their own secret weapon. Even gave her a way to devour people-- what they didn't count on was her testing her new capability upon them.
The metal girl isn't mean. Or cruel. Really. She's just very flawed in her programmed emotions. And now that some idiotic mechanics added the feeling of hunger to her programming, she has no moral issues devouring anyone she needs to.
Besides, this way she never has to wind herself up as much. Digesting people is a much more efficient source of fuel.
"So strange, they scream..."
Battling is battling. Vore battling can't be THAT hard.
Passives
Ball based-- Most of Orianna's move use her electrical ball. She can use most moves no matter where she herself is unless her ball is somehow removed.
Winding-- Orianna requires winding up! She has 26 health but loses 2 Hp every turn. At 0, she is stunned for 5 turns as she winds up. (She rolls 2 d6 to see how much HP she regens with.) If the opponent deals 10 damage to her while she is winding up or if she enters this stunned phase in the final stage of any vore, THAT'S when she loses. If she digests someone in a multibattle, they heal her for 3d6 health.
Metal-- She takes 1 less digestion damage
Actives
Command Dissonace-- The ball electrocutes her enemy. If successful, deals 2 damage and gives a -2 next turn. If Orianna is holding the opponent, she gets a +2 next turn.
Command Attack-- The ball rushes forward and rams into the enemy, stunning for 1 turn. If Orianna is holding her opponent, the ball rams the enemy one stage into her.
Program glitch-- Some fragment of her programmed "personality" determines that her opponent has a burning desire to know what's under her dress. She obliges, sitting her metallic rump right onto their face. "Ball based" does not effect this. Gives them a -3 for 2 turns.
Command Protect-- Only useable if she is outside her opponent. The ball negates the next damage she would take that isn't a Finisher.
Finisher
Command Shockwave-- Only useable if Orianna is outside. Orianna sacrifices half her current health (or windup stacks) to send out a pulse, throwing the enemy into the ball. If she loses this roll, she loses all hitpoints and is sent into "winding stunned" phase. If she wins, they go straight to the final stage of Ball Vore.
Ball Vore
Orianna holds B - Ball opened - B beginning to enter Ball - B fully inside Ball - Ball closed, B begins being converted into electricity. 2 damage, 19 to break. (Note-- Escaping from B beginning to enter ball and earlier immediately puts them in control.)
Oral Vore
Anal Vore
Orianna holds B - B in metallic exhaust hatch (anus) - B in exhaust pipe(rectum) - B being converted into energy (2 digestion, 14 to escape.)
