Name: Surius Sarcalla (pronounced soo-RYE-us sar-CALL-ah)
Gender: Technically none, but male in appearance and voice synthesizer.
Species: Sentience-Having/Emulating Robotic-Automaton, usually shortened to S.H.E.R.A, or, for convenience, Shera
Alignment: Lawful Neutral.
Powers/abilities: Flight, using a series of boosters in his feet and two sets that can flip out of his back. A self-healing body, up to a certain extent, though this isn't infinite. Very slight abilities of transmutation, though only for small amounts of stuff at a time, and only to and from nonliving stuff. Highly modular build, so pieces can be put on, taken off, and shifted around the body in almost infinite ways. Has a plasma/energy creation and control ability, which would entail electromagnetic abilities as well, but he can only create small amounts at a time.
Tools/Weapons: His hands can shift into many different types of bladed weapons or ranged cannons.
Appearance: I'll draw something up eventually, but for now, just think a very smooth, bright-silver(almost just a shiny white) humanoid, with many tiny lines going along his body, most too small to be seen without intense scrutiny, though there are a few bigger ones, glowing a light colored, but dull green. His face is almost without feature, except two eyes, slightly bigger than would be on a human, that glow a bright green.
Personality/Bio: He's fairly blunt, and highly intelligent, made to follow a certain set of rules, and to an extent, enforce them. The Xir'algath, however, break these rules, and are causing chaos. As such, they are to be dealt with.
Despite his emotionless appearance, he does, in fact, feel, but he, along with the rest of his species, are just programmed to be able to hide their emotions well, as showing them openly can be seen as detrimental in society, as they have witnessed. He came to this planet after hearing of the invasion, and, in his ambition, he wanted to stop it before it reaches his home and his people.
Name: Ciestaal Suul (see-es-TALL SOOL)
Species: Cryriis (cree-ris)
Alignment: Civil Good
Powers/abilities: Can manipulate his aura into many shapes and weapons, including laser-like projectiles and even solid weapons. On top of this, he can manipulate it into bending light around him, rendering him and/or others invisible, or can manipulate it to "align his energy with that of other objects," allowing him to walk on walls and ceilings, and even float down slower than gravity should really allow, and even seemingly adjust his weight at will. However, he only has a limited amount of this "soul energy" to draw from, so he can't just create infinite things. Can sense other people's auras, but cannot control them.
Tools/Weapons: All he has physically seems to be a red crystal ball that floats around him in seemingly random patterns, but never straying far from him, and it seems to be near indestructible, but he has no control over what direction it goes, really.
Appearance: He wears a red mask over his face, with a dark red, long sleeved robe going down to his ankles. Under that is a dark grey chestplate, with shoulder armoring peeking out through holes in the shoulders of the robe, along with other armor underneath the robe, but not visible, except for his armored hands. He also wears a black scarf, very baggy near his neck, with two long tails, with shaggy, dark grey hair covering the rest of his head that the mask doesn't.
Personality/Bio: He's a very spiritual person, speaking of the need for people to be "in tune with their aura" and many other such things. He usually tries to preach peace, but knows that, unfortunately, there is sometimes need for force. And this is one of those times. Even in battle, he keeps a calm, tranquil demeanor about him, rarely ever showing fear.
