Updated Limeblood headcanons because I’m always a sucker for them (this is based on my TLG AU)
- The OG trolls, their species originally had lime green blood before it split into the twelve castes we know today
- Multiple variations depending on where they lived
- Amphibious, but could lean more towards land or water
- Didn’t worship the gods, but held them in high regard and respected them; what I’m saying is that limebloods were chill with gods but weren’t afraid to tell them they were wrong
- Capable of healing, mind control, empath abilities, powerful telekinesis and channeling immense destructive power; definitely the most powerful of the castes, even rivaling the fuschias
- Limebloods have naturally white hair; the Avysos are all mutated limebloods, so they have dark hair
- Because I really like the headcanon of limebloods being water-aligned, they mainly lived along coastlines and lakes
- Since all castes seem to have their own “thing”, limebloods were the healers. While it has been widely-erased from Alternia, they are responsible for eradicating a lot of diseases, and their cures and practices are used in modern times (albeit without credit)
- Alchemy was common practice
- Before they were wiped out, limebloods were banished from Alternian society and forced to live out in the wilds. They thrived for a short while as independent colonies with their own Mother Grubs, before Doc Scratch had Condy kill them all as well as most of the Mother Grub population
- This mainly done out of fear of a possible lowblood rebellion as limebloods, while peaceful, had the power and drive to turn the tides (although they just wanted equity and for everyone to stop murdering each other jfc Doc Scratch)
- While lower on the hemospectrum, limebloods were the closest relatives of tyrianbloods (possibly another factor into why HIC wanted them gone) but also share a majority of their genes with goldbloods
- They have a very strong bite
- On Earth C, limebloods are brought back but are treated as spectacles and their culture is kind of disrespected so they mostly live away from society (this started changing once their gods returned and stuff)
- While they mostly do healing and spiritual practices, limebloods are capable of doing the exact opposite with their abilities and worship the outer gods and can even control them (similar to Rose’s Grimdark mode) Examples include using telekinesis to draw the breath/water from bodies, triggering illnesses, literally draining the life from others and even skipping all that to just using the sheer destructive power they can wield. Yeah, don’t fuck with limebloods, guys. Seriously.
- They can use incantations and speak in an old language that predates even Old Alternian. It sounds similar to the language of Horrorterrors.
- Karkat is a mutated limeblood, but while he lacks in psionics, he might have some mild empath abilities, something that’s shared amongst the Vantas fam
- Limebloods were naturally more pragmatic and empathetic, which is why when the hemospectrum became a thing they were were the first to say “that’s dumb as shit lady why the hell would you do this?”
- This is only slightly related to limebloods, but all blood colors had a general lifespan range (around 100 years/50 sweeps) before Doc came along and ruined that because Doc Scratch sucks
- Sopor slime was made from ground-up limebloods in the past, it’s now made from an artificial recipe that sort-of copies the compounds of their blood
- This is why Mari doesn’t have a recuperacoon, if anything sleeping in an artificial version of the blood of her caste would make the bad dreams worse
- Diets consisted of fish and plants, occasionally lusus meat
- Didn’t do parents, were assigned “mentors” at birth to raise/teach them
- The first limebloods probably terraformed Alternia into what it was
