Sveinx was raised by two starkly different parents and this conflicted, mix match that somehow managed to compliment each other. This has created a constant struggle of conflicting dominate traits within the Redleaf. From Aether he inherited his father's own acute curiosity. He's an extremely intelligent individual and tends to be rather observant, because of this. Though his crude (and vulgar) way of speaking, favoring “slang” over the actual full pronunciation of words gives an entirely different illusion. Like his mother he loves how the rough, crude words fall from his lips. He is fiery and feisty like her. He is very 'in your face', he will tell you exactly what is on his mind without a second thought. He is brutally, bluntly honest and that doesn't exactly earn him easy friends. Though not as smooth with his words (though this is primary by choice) as his father, or even his brother Custard, he is still witty and, if you get past his rough, thorny exterior even funny. He's adopted something of a carefree, playboy “persona” and is known for his being flirtatious and coy. Most of his traits were taken from his mother, of whom he always was a “mini-me” of. On the upside of the coin, Sveinx isn't as arrogant and promiscuous as he puts out. He did inherit more than just his father's intelligence capacity. Like Aether, Sveinx is fiercely loyal (though both parents were loyal respectively). When he gives his word he does everything in his power to make sure that he keeps it. Despite his very 'in your face' behavior Sveinx actually fairly diplomatic. Though he is certainly far from afraid of the fight he knows that it is the last option, the last resort. In reality, he isn't as half the villain he likes to paint himself as.

Over time Sveinx had mellowed out, taking to be a bit more like Aether, but not much. Personality wise, he hardly “changed” at all, more-so he simply adopted a more passive aggressive fire, and seems to have widened his patience capacity to an eerily (for him anyway if one were to know him in his rambunctious youth) long measurement. Or, maybe, it was that he had learned the skills that were required of a leader when he was promoted under his parents’ rule.
