Although much is unknown about Tesseract's personality, it is shown at the end of Mortal Coil that he had no regrets in life and he did what he did because it was life. He appears as a stoic and powerful mage with a mysterious background, but in his dying stages he states that he will miss his cat, and his dying wish was to see and feel the sun on his face without the mask which keeps him alive. It is evident from this that Tesseract isn't a completely heartless killer, as he values sentimental things. He appears to be a deep thinker and acknowledges the fact that he makes mistakes. He also has a cat which is just called "Cat" he seems to have great fondness for it, saying he will miss her when he is dead.
Tesseract is an adept mage with a rare ability called Bonebreaker. It is also evident that Tessearct used his magic effectively and could take down even groups of extremely proficient mages including; Tanith Low, Valkyrie Cain, Skulduggery Pleasant, Ghastly Bespoke and Erskine Ravel.
While he is not described as possessing superhuman strength as part of his magic, he is an enormous man with a massive build and a large amount of muscle mass, granting him enough strength to overwhelm any opponent without superhuman strength. He is also shown to be incredibly stealthy, sneaking up on both Tanith Low and Davina Marr without making a sound, feats made more impressive by the fact that both opponents were in fortified locations at the time. He displayed a high level of martial arts and combat skill during his murder of Davina Marr, countering or defeating all attempts to capture him despite being heavily outnumbered. Finally, he is shown to possess a high tolerance for pain, fear and stress, as demonstrated by his refusal to be cowed by being buried alive and his stoic attempts at completing his goals at any one time, no matter how he is injured or what happens to him.
Tesseract parks his truck on the outskirts of a field, moving into the trailer being pulled behind it. He looks over the array of masks up on the wall. He picks out one with a blank experession on it, he's meeting a new "client" today and he doesn't want to give the wrong impression. He pulls the mask he is currently wearing off, feeling the cool irish air on his face. He doesn't look in the mirror today, he doesn't want to see how his face will be disfigured today. He puts the new mask in place, feeling the hiss as the needles sink into his face keeping the rot at bay for another day at least. He steps out of the trailer and looks around, unsure as to where his employer wishes to meet him. All he was told was to meet them here, in this field, near a building of sorts. Shrugging to himself, tesseract decides to walk futher into the field, the mud squelching under his boots. After a few seconds of walking he spots a small building in the distance and changes course to head towards it.
As he approachs he realises that it is some sort of crypt with a scorpion engraved on the outside. Once he gets to a few feet of the building he hears the creaking of a door opens and part of the crypt slides open. A woman walks out of the door and immediatly tesseract is hit by a strange emotion, one he has never felt before; Love. Tesseract mind is clouded with nothing but love for this woman, an unyielding desire to be forever at her side. Then almost like a haze being lifted his mind is banished of these rediculous thoughts and he realises exactly who he is dealing with.
"Tesseract I assume" comes the reply, her voice playing with the words, a question as much as a statement. "I wasn't sure if you would be able to find me at such a remote location"
"Of course I would come, I'm an assassin after all. I'm used to people finding the most secluded spot possible to conduct business with me". The woman nods her head but does not speak and tesseract waits patiently for to continue. She turns her back to him, gazing at the building.
"You know tesseract, this crypt is my own family crypt, all of my family is buried here, well at least the ones ones who are dead. See that scorpion, that is out family crest and my grandmother always used to tell me that a scopion never changes it's nature. Back in my misspent youth I believed her, believed that when the dark gods returned that when they would possess me that unlike the other heathens we would meld with them and be able to harness there powers without losing all of our induviduality. I was a fool back then, arrogant, young and brainwashed and it lead me down the road of violence. But now i've grown past all this and become the woman I am today, still arrogant, still young but most certainly not brainwashed"
The woman sighs before turning back to tesseract and it is now that he notices the file she is holding in her hands. She takes a step towards him and holds it out, watching him through narrowed eyes as he takes it from her. "Inside this file you will find what you need to complete your job, names, locations and times, and most importantly a picture of the man you are to kill". Tesseract tears the top open and pulls out a picture, frowning as he looks into the calming blue eyes of the man pictured before him.
"I hate to pry into my clients personal lives Miss Sorrow but this appears to be a picture of the sorcerer by the name of Mr Bliss. I like to make a file on people I am likely to end up killing and this man is none other than your own brother"
"That is indeed correct. I've tried to kill him myself 3 times already but he just won't stay down. I've tried other assassins too but they all failed. I've been told you are the best around and quite frankly if you can't kill him then i'm not sure who can"
Tesseract nods his head and slides the picture back into the file. "I'm afraid to say Miss Sorrow but for such a high profile target I'm going to have to ask for double my usual fee, I don't like to put myself at extra risk without extra reward". It's the woman's turn to frown now but it only registers on her face for a split second. "You consider my brother to be a high profile target" she asks inquisitively.
"Well he is, physically speaking of course, the most powerful man in the world and thus he commands a significant precence in the magical community. Killing him will not be easy and will send ripples spiralling through our society for decades to come-"
The woman holds out her hand to stop him and he obliges. "Very well then, I'll pay you extra, just make sure do kill him and once you do kill him, make sure he really is dead. I've had this problem before"
"Of course Miss Sorrows" tesseract replies and tilting his head slightly as a show of respect he turns and walks away, leaving her standing there, China Sorrows; the most beautiful and dangerous woman in the world.
Winner: Mr Bliss
Expert's Opinion Edit
Bliss won because of his legendary strength and high durability which allowed him to shrug off most of what Tesseract could do to him. Tesseract may have been the superior fighter but when your opponent is just that strong then all the fighting skill in the world can't win you the fight.
