Elijah

Elijah's need for sleep can be its own fuel source. Seriously, she sleeps for several hours a day, and even for several days at a time, likely due to her being narcoleptic. Also 30% of her body is mechanical and she can sleep pretty much anywhere. Which resulted in her suffering from radiation poisoning. (she fell asleep around radioactive material once) When she isn't sleeping, as rare as it is, she is extremely laid-back and a theorcrat. On rare occasions she leans into her machine worshiping tenancies

Appearance wise: she has brown pajamas, rosy skin, short brown hair, and her eyes got used to being closed almost indefinitely.
