- Ciel's Venom - Ciel (The snake(s) behind Lu's back) is able to produce venom of varying effects, example include: Standard Harming, Blinding (if applied to the eyes), Numbing, Paralyzing, and a venom that causes your muscles to spasm uncontrollably

- Extendable Snakes - Of course, what use are snakes on your back if you can't extend and expand them properly? LuCiel is also able to hide Ciel inside his back if he wishes.

- Lu's Superhuman Strength - Quite self explanatory, body's is as much as 5 times more powerful than a normal person with the same muscle size

- Power-Switch - This skill allows LuCiel to control his two two main skills (Venom and Strength) so that Lu is able to use the Venom by secreting it from sweat pores and fangs, and Ciel is able to have super-strength. What this means however, is while both entities can have both abilities, the both of them can't use the same ability at the same time. TL;DR: Ciel can be strong, but not while Lu is super-strong himself

- Personality Switch - While most of the time, it is Lu who is the main conscious and has control of both him and Ciel. When Lu loses mental strength, Ciel may take over his body by force. This will turn both of Lu's eyes red (they are originally both yellow), and LuCiel will become more relentless, vicious, and even insane. He will no longer use tactics and will use all of the power possible to defeat, or even kill, his enemy.

- Current Combat Style: None in Particular - Basically has no martial art training; subject to change.

- Both Lu and Ciel will die if one of them dies. But you need to kill all of Ciel's clones if you want Lu to die with him. Which my prove to be difficult because of LuCiel's ability to hide Ciel away in his back

- Frost, or anything chilly, snakes don't like that, nor do humans that don't produce heat

- While LuCiel is capable of withstanding the impact strength of others as well as his own. He is still very vulnerable to swords and cuts, like a normal human.

- LuCiel's most direct weakness is that the upper spine of Lu's back. Where Ciel originates. A good, solid hit to this spot will paralyze LuCiel completely.

Once upon a time, not too long ago, there was a young boy, named "Lu". Lu had a somewhat healthy obsession with snakes, logically caused by living near a zoo specialized with the reptiles. Lu of course, went to this zoo a lot, eventually going there without his parents, and made friends with of only the care-takers, but many of the snakes too. He merely played and fed the little ones at first, even though he was trusted by the staff. Months passed before he even trained some of the bigger ones, ones that are just as big as he was. Then, a one of his favourite snake's laid an egg, before passing away. Overwhelmed as if he had lost a loved one, he had a driving desire to protect the egg, and what comes out of it.

It wasn't until the little snake became slightly mature until he was able to take care of it, like the snake's parent. The zoo-keepers even let him name the snake, "Ciel, Together, we'll be the Lu/Ciel Duo!" Together, the two created an unbreakable bond, as if they were brothers. Later on, the zoo-keepers let Lu take Ciel home with him, his parents weren't completely taken back when they saw a snake acting as a scarf on Lu when he came home. Ciel was never a threat to the Croxford family, but was otherwise to those who threatened it. But at that point, Ciel was only able to kill by constricting.

A few years later, Lu found himself chained to stone slab, without an explanation, who would have knew that the Lu/Ciel Duo would be complete at that point? Experiments were made to both the poor young man and snake, eventually giving Ciel the ability to produce a dangerous venom. Neither of them remembered how long did the torturing last, for they have not seen the sun, nor much else other than inky darkness. When they were finally released, Lu notice a change, he no longer produced heat by himself, nor is his tongue thick, but thin and forked. He could feel a strange slithery sensation on, no, IN, his back. It was Ciel, and a couple of clones of him, fused into his back, together they are now "Luciel".

Now, the reason why Lu and Ciel were fused into one and were given powers beyond any other human is because they were meant to be a super-soldier. But the brain-washing part partially failed; only Ciel was affected. After release, Lu can not bring himself to accept his new body, he never had. Because of the specialist's attempts to keep him in check and such, at one point it angered both Lu and Ciel. Leading to a total destruction of the facility. The specialist were not prepared, assuming that the partial failure in brain-washing wouldn't reflect on them badly, and were dispatched quite easily.
