Age: 291yo (Eridians live appx. 689 Earth years)
Gender: Hermaphroditic (He/Him/They pronouns)
Notable physical traits: Rockyâs about the size of a labrador and weighs over 300lbs. Like all Eridians, heâs made of oxidized material; his bones are metallic alloys and his blood is liquid mercury, which makes it silver in color. Essentially, heâs steam-powered. Extremely hot to the touch. Receptors on his outer shell detect sound and send those signals to his brain, similar to the way humans experience touch (he has no eyes and canât see the way we do).
Extra notes (headcanon tag):
Rocky has photographic memory. He claims this doesnât necessarily make him âsmart,â just that heâs able to take in information and not forget it. Argue with him at your own risk. You may have forgotten something you said the other day, but he remembers and will shove it in your face to prove his point.
His speech patterns are musical, and he can make at least five different notes at once while speaking. The octave drops and lifts to convey moods.
Rocky and his crew were the first to leave Eridâs orbit. Until then, Eridians only explored within those constraints; they actually have somewhat of a space elevator that brings them from the equator up into the planetâs orbit.
One Eridian year is 42 Earth days. One Eridian day is 5.1 Earth hours.
Erid is extremely close to their sun. Despite that, itâs pitch black due to the thick atmosphere blocking out the sunâs rays.
Rocky has a mate (Adrian) who heâs been with for nearly 200 years. Eridians mate for life, and they lay eggs to reproduce.
Eating is a quiet, private activity for Eridians, contrasting the social aspect of human culture. Itâs not enjoyable. Itâs just necessary. And itâs considered rude to talk while doing so.
When Eridians sleep, they go into a paralysis. No cognitive functioning occurs during that time, and they canât be woken up. This is why Eridians watch each other sleep, as they need to be able to provide protection at their most vulnerable.
Eridians can hear much higher and much lower frequencies than humans. If you have one of those ultrasonic pest repellants in your house, Rocky will go berserk from it. Be warned.
Rocky can be incredibly bossy and impatient at timesâmainly because humans in general seem âslowâ to him in many areas heâs fast. Most of the time, itâs not meant to be an insult. Sometimes, it absolutely is.
His ability to âseeâ his environment comes from a form of echolocation. Rocky is constantly emitting high-frequency clicks and maps his surroundings based on the echoes that come back. Other times, he taps to create a louder noise and determines from that.
Eridians do not have a sense of smell, but they have a sense of taste, which is close enough to understand what smell means.
Despite his impressive engineering knowledge, Rocky is less acquainted with modern electronics. Eridians havenât invented the transistor. He struggles to understand Earthâs technology, but can make sense of it, given enough time to putz around.
Thereâs no real âfrontâ or âbackâ to him. All five of his hands can be used interchangeably, and he can move in any direction with ease.
Eridians donât have an immune system. Itâs very uncommon that they get diseases, and when they do get them, theyâre likely to die if the disease is fast-moving.
Rockyâs voice warbles when heâs being a snarky POS.
