Clara (lucario)

Lawful/neutral

Clara was born as a riolu in a pack of lucarios (not savages, but also not the most civilized)
Her mother was the lowest ranked member of the pack, & so they both were constantly harrased and bullied by the others
One day in a moment of weakness, she tried to escape, but was unfortunate enough to step right into where a human would be isekai'd
- She became enveloped in light, and the 2 souls merged into 1 body, Clara's body
Had to learn how to take care of herself after she was banished for lashing out
Keeps an stoic facade to hide the fact that she's very akward and a very bad socializer
Doesn't understand the nieches of communication, like subtlety or double meaning, sometimes coming off as blunt or rude
Some days, she doubts if the voice she hears is really a human or her just becoming insane
She's the one that named the human "Smoke"
Having to feed way more EXP than normal to her 2-souls-body, she spent half her life training just to keep up with others
Every time she gets to relax is a blessing for her
Hates people who manipulate or beat down on others
Deep down, fears losing those close to her
Self teaching aura expresser and fighter

Came from another world, has some form of amnesia since he doesn't remember his name (or any kind of name from his past life, or how humans used to look)
His first conscious days were spent being dragged around against his will, watching through Clara's eyes, trapped inside her body
Took weeks for him to learn how to speak, and months until he could move on his own
- They don't talk through telepathy, they have to physically say whatever they want the other to hear (though only one of them can be heard by others)
His presence can be felt by a feeling of creepyness and uneasiness coming from dark places in a room or shadows. Lots of light (natural or artificial) mitigate this effect
If a room is already dark, he suffocates any lightsource he's near, rendering them quite weak, if not outright useless
Rather lonely, since only Clara can see or hear him. He can't touch or feel things normally (only through Clara)
Incredibly bitter at the world (for his predicament) & hardly trusts other pokemons.
Can help Clara by using a move at the same time as her, or help her control her aura, or scout ahead as an invisible ghost spy (range of a couple dozen meters). Mistery dungeons heavily restrict this last technique
Fears that one day Clara will wake up and he'll dissapear, or that he'll wake up in Clara's place
Self teaching aura senser
