It is uncertain if this is simply a highly developed skill or actually a power, however Jayce possesses an inhuman aptitude for mastering languages. In his time on Earth, he mastered Japanese, several dialects of Chinese, as well as English, French and some German.

This is a unique combat style known only to the Setsukovian temple guards and while it is typically taught from master to student from youth into adulthood, Jayce appears to have mastered the style by pure instinct. This open-hand combat style involves a lot of crouching, use of the full body, swipes specifically to compromise an opponent's stability and footing, and vital point strikes.

Because Jayce spent much of his life on Earth hiding his eyes while in public, he has learned to rely on his other senses to guide himself as much as his actual eyesight. His senses of smell and hearing are uncanny, being comparable to a tiger in both regards. When his eyes aren't covered, Jayce is able to see in any level of light, including pitch darkness. Jayce's sense of taste is only slightly more advanced than that of a human, having benefited only slightly from the olfactory connection to his sense of smell. His tactile senses, though, are capable of discerning a great level of detail through his fingertips -- a skill he acquired while working to dress geisha blindfolded.

Jayce appears to have inherited an ability granted typically only to the High Priestesses of Raiikechien-- he is completely immune to being involuntarily compelled against his will. He cannot be mentally subverted, magically manipulated or in any way forced to act in a manner that he does not wish to act. It is through this power that the High Priestesses are able to ensure their impartiality in all judicial matters and remain free of anything that would otherwise jeopardize their independence. As a side effect of this ability, Jayce possesses a high resilience to any foreign substance that might otherwise affect his health, including poisons, drugs and diseases. Jayce also recovers from physical damage rapidly, regenerating scrapes and bruises in a matter of hours instead of days.

Jayce possesses cat-like reflexes that allow him to not only land on his feet from almost any fall but grants him incredible flexibility as well as the ability to move both lightly and silently.

Jayce possesses a limited form of precognition that allows him to sense and anticipate impending danger. He does not possess enough of a prescience to warn others, merely to act in an effort to avoid the danger.

By harnessing his chakra energies and focussing them into a single point in the center of his hand, Jayce is able to release an explosive beam of concussive force equal to 500lbs per square inch with a maximum range of 500 feet.

Through use of this second level attack, Jayce is able to generate a vortex of positive and negative chakra energies that assault the target by creating a cascading imbalance in their own chakra, often with devastating results. The less control and concentration the target possesses, the more vulnerable they are to this attack.

This elite level attack is perhaps Jayce's strongest to date. Unfortuantely, due to the extreme amount of time required to sufficiently charge the attack and the fatigue Jayce suffers as a result of its use, this often mandates its use as an all-or-nothing alpha strike. Since any living victim would have to be unaware of the attack or immobilized, Jayce generally refuses to use this ability against a living target.

By activating this secret justu technique, Jayce is able to fold his chakra energy around himself such that he can appear to be in multiple places at once. This is, in essence, a manipulation of quantum time as Jayce is revealing temporally displaced shadows of himself. The more he creates, though, the more his energy levels are drained and the less tangible the duplicates are.

The more advanced version of the Bankyou Doutai technique. Through use of this technique, Jayce can create a seemingly unending series of duplicates, but while briefly more powerful than those created by the Bankyou Doutai, the duplicates of the Mugen no Bunshin are far more short-lived, remaining only for a few minutes before dispersing once more.

As a result of the Savage Trial, Jayce has acquired the ability to manifest the appearance and abilities of a tiger, growing white fur, a tail, claws, and accentuating his already cat-like senses and agility. Further, while in this hybrid form, Jayce is twice as strong and twice as fast as his normal trafari form.
