Ang finally gets a ref post, and also a redesign. By the way, he's 5'9" (172cm). He weighs 120lbs. (54kg), so yeah he's skinny. I also aged him up to 7 sweeps because he just doesn't seem 13 year old material even for trolls.

SHENANIGANS:
Land of Desolation and Lakes, consorts are seagulls (which, unfortunately for ang, like to prey on fish). His denizen is the Loch Ness Monster, aka Nessie. (IT LIVES IN A LAKE, HIS PLANET IS THE LAND OF DESOLATION AND LAKES GET IT? haha)

He's a Derse dreamer (obviously, since he's on the blue team)

Sage of Rhyme. A sage is a wise man (which makes sense as Ang is pretty intellectually strong) and "Rhyme" because he likes books.

His Lusus is a gulper eel. It doesn't eat other lusii (most of the time!) and feeds on small creatures that live in the surrounding ocean. However, Ang has caught it with some oddly coloured blood stains on its teeth.

Symbol - Laguz. It's the lake rune, and looks like a straight vertical line with a diagonal line protruding from the top facing left. His horns resemble his symbol - both are straight up, and the left is hooked like his symbol.

His blood is perse (#550b68), and he's between Gamzee and Eridan on hemospectrum

Strife is 2xpistolKind. It's alchemized with a steampunk novel and soap. He almost made broomKind his weapon though.

Captchalogue - Card Catalogue modus. It allows for quick retrieval of objects and the cards are all sorted alphabetically. This would prove a hassle for most trolls especially those with organization problems, but Ang doesn't have a problem.

Trolltag - ballisticHyperdrive. Keeps his mood on DETESTFUL. He replaces l's with 1's if flustered/angry but uses correct grammar and punctuation otherwise. He also has a tendency to use big words.

Quadrants-
♦ - Arancio
He and Arancio have been friends since they were about 3 sweeps old. Arancio teases him about lots of things (i.e. his obsessive cleanliness, his weight, his hair....everything), but they both are very close. Ang wishes he could be in red with her but Arancio only sees him as a friend (or moirail, since FRIENDSHIP ISN'T AN EMOTION in troll society).

♠ - Bravio (unrequited on Bravio's end)
Bravio hates Ang for stealing Arancio from him, and Anguilla is fully aware of this. But he mostly sees it as a trivial manner and shrugs Bravio off despite multiple attempts from Bravio to piss Ang off.

Ancestor - The Scripter
His ancestor was a scribe, and therefore regarded highly in society. He kind of screwed up his honor by hooking up with Arancio's ancestor though.

His name means eel (Anguilla) and royalty (Majestas) in Latin. So literally "royal eel". Yes, I am aware Anguilla is a Caribbean island but i don't feel like changing it deal with it.
As for his trolltag "ballistic" refers to his weapon, and "hyperdrive" refers to his love of science fiction. (For the uninformed, a hyperdrive is, in science fiction, a device which allows a space vehicle to travel faster than the speed of light, entering hyperspace; also, the state of such space travel. definition taken from here)
