Righteous fury always bubbles just beneath the surface, but Karran Val'teo knows that a bonfire may burn bright, but a plasma torch will melt durasteel. The Dark Side is a powerful tool, but not to be indulged in lightly. Immense focus and self-control are required for the most effective application of its power. Karran strives to embody this balance, but fails as often as he succeeds.

Karran Val'teo spent most of his adult life without a family. Subconsciously, this has turned him into a chronic caretaker. Every opportunity he gets, he invites someone who needs a place to stay into his home. On several occasions, he has built extensions and additions onto his home just to accommodate his guests. These gestures do not end with sentients, however. It is not uncommon for Karran Val'teo to adopt animals that others will not, just so that they might have a chance at a happy home. While this generosity does bring many people together, it does leave him open to being taken advantage of.

Karran Val'teo willingly underwent a scientific recreation of an ancient Nightsister ritual in an effort to bolster his own strength. An unforeseen side effect is that it seemed to blunt some of his higher though processes. He is significantly more direct, impulsive, and seems to lack many of the self-preservation instincts that most people do. He is not more cruel but simply more capable of cruelty, as one can expect when Dark Side Magick is woven into your very being.

Karran Val'teo has fought with almost everyone he considers a friend. And each of them has left their mark. There's no hard feelings, besides, what's some bloody knuckles and internal bruising between friends? However, this aggressive nature can be off-putting to some less aggressive acquaintances.

Karran Val'teo approaches combat like a trained attack beast. Singular focus, dogged determination, and nearly rabid ferocity. He is not the one calling shots, but he is the one you put at the front of a charge. His single-minded approach to combat lends itself to being highly effective against single targets, but can leave him open to surprise attacks.

Karran Val'teo's dedication to incorporating various aspects of his Zabraki heritage into his life have even extended itself into his combat with a lightsaber. Although the Djem So lightsaber form typically requires a solid stance in order to deliver its powerful, dominating blows, Karran Val'teo has taken to incorporating the fluid movement of K'thri and sweeping kicks into his attacks in a duel. While this sacrifice in footing does add a degree of randomness to his attacks, making them harder to predict, it does decrease the power of his strikes with his weapon.
