sublimate

Canon Abilities (100%):
Kanda has radically enhanced healing and regeneration abilities which have brought him back to full health even from what would clearly be otherwise fatal wounds. He can withstand attacks that would kill a normal person outright—that akumas' virus doesn't affect him; he's been nearly cut in two and has healed from it; he's even been shot in the face by an akuma and healed almost at once. He’s also effectively been “killed” in canon—his body literally shattered into pieces, only to awaken again a few minutes later.

There is, however, a limit to this regeneration (though what and where it is remains unspecified). Kanda is repeatedly told to be careful and not to squander his life force. At some point, the battery on which his regeneration draws will run out, and it has clearly been deeply depleted during recent canon events. The apparent power source (or at least the barometer) of this ability’s functioning is at tattoo-like Om symbol over his heart.

Kanda's primary abilities are as a swordsman. His katana, Mugen ("Six Illusions") is his anti-akuma weapon through which he can activate several abilities. Technically, most of these are powers "housed" in the sword, but they're not abilities of the sword's, per se. Kanda's Innocence (the substance that makes an anti-akuma weapon work) is an equipment-type, which means that Mugen took its form for him and only he can activate it.

We've thus far seen Kanda use the following:
Kaichu Ichigen (or "First Illusion: Hell's Insects")—releases a swarm of a dozen or so supernatural insect-like creatures. This effectively gives Kanda a ranged attack, as they fly out from the sword in an arc, attacking once and then disappearing.

Nigentou (or "Double Illusion Blades")—encases Mugen in a sheath of light which is then mirrored as a second katana, made purely of energy, in Kanda's other hand.

Hakka Tourou (or "Eight Flowers Praying Mantis")—used in combination with Nigentou, this is a quick series of eight slices, with the resulting cuts resembling a flower.

Shouka (or "Sublimate")—it's not completely clear whether this is one of the abilities Kanda activates with Mugen, per se, or if it's more one that he activates in his body directly, but it certainly works with the abilities of his Innocence. Shouka seems to be an activation of Kanda's Om tattoo more than anything, and by doing it he can actively sublimate his life force, making it available as a sort of battery for combative strength.

Sangenshiki (or "Three Illusions")—increases Kanda's speed and strength dramatically by drawing on the life energy made available by Shouka. (When Kanda uses this ability, his eyes change, the pupils becoming solid with three dots.)

“Fourth Illusion”—a further increase to speed and strength, again drawing on Kanda’s life force. (In this case, his pupils show four dots.)

“Fifth Illusion”—seemingly a further sublimation of life force that has two separate ranged attacks associated with it. The draw it makes on his life force is damaging both psychically and physically, apparently resembling something of a berserker rage that impairs his rational capacity. Electricity and light spark from Mugen when the Fifth Illusion form is activated. It also makes his hair turn light purple.
• “Fifth Illusion: Ripping Flash Claw”—an energy attack emitted as targeted rays of light from Kanda’s hand.
• “Fifth Illusion: Explosive Spirit Slash”—another energy attack; this one does slashing damage to a target from afar, but it is delivered through the motion of his hand, not his sword.

Class: Swordsman

Canon Abilities (25%):
Kanda’s healing and regeneration abilities, though still faster than normal, will be reduced. For practical purposes, he won’t be able to regenerate limbs—perhaps over a span of decades he might, but it would be too slow to register in game play. He might re-grow a lost fingertip in months, but again the process would be slowed radically.

Since much of the time it’s his sheer stubborn will that keeps him on his feet and fighting, he will retain that, but his general healing rate will be 75% slower. He will remain difficult to kill outright, but it will take comparatively less to bring him down in a fight so that he stays down and appears “dead” for some length of time—hours or the better part of a day before he can reawaken, as opposed to the scant few minutes it takes in canon.

As for offensive abilities, he will still be able to sublimate his life force, but it will drain him far more quickly. He will be able to activate Nigentou and Kaichu Ichigen (though there will only be three or four of the insect attackers, not a dozen), but he will not be able to use either right away. The abilities will only return gradually as he adjusts to the new world he’s in. They will never be as strong as they originally were, and of course, he must be wielding Mugen to use them.

In

vigrith, Mugen will have additional properties as a holy weapon.
