Octavia has had a few nicknames.. not all of them the best.
However, when I think of her, I think of Red. Red is something she goes by because while just a basic color it is something she has based her life around without even knowing it. She embodies the strength of the color, She demands respect and commands the room. Her red hair makes it easy to find her on the battlefield, busy street or vast space station. Red is the path she chose to follow as a Sith, Red is her personality. Firey, quick wit and a wicked temper. Red is the color she used to tattoo her back to dedicate herself to her second husband, It's also the color of the blood that runs through her veins, the blood she spills of her enemies, and the legacy she hopes to leave to her daughter someday.

While it is a simple color it is one that describes her to a tee and she proudly goes by it.

Khryso Mallus - The Gentleman

Khryso is always striving to present himself as an upstanding, cultured man. He wants people to see him as the height of civility and society. Striving for luxury and power, "The Gentleman" describes just what it is that Khryso aims for. While he is still a work in progress, the facade is almost as important as the man himself and hopefully one day they can become one in the same.

Ahsik “The Echo” Warren

Ahsik depends heavily on his ability to make Illusions and dupe others into believing them real. Often times it manifests as extra limbs or phantom strikes, even as illusionary clones. This gives the appearance that when Ahsik moves he has an “echo” following or leading him.

"Doctor Dolittle" - Tybalt
He loves and cares for all the animals in a way that feels like he speaks their language.

'Her Bitch' - Because everyone, and I mean everyone, knew who wore the trousers in the Mimosa-Inahj marriage.

Thanadd's piranha mouth was already pretty gross before his jaw was mangled and cauterized by a lightsaber. I'd say he'd be known as "Putrid Pau'an," as the stench of his breath underneath that collar is unimaginably gnarly.

I think the best one for Tahiri is The Beast Tamer.
But for you pleasure here are some other's for Tahiri: The Nice Sith, The Awesome Dragon lady, Little Dagger (by her Father), Hiri (by her brother's),

Ronovi - The Juggernaut

Scudi - The Scavenger

**Khryso - The Crisis Man**
