DIAMOND
Jacky can turn his body into organic diamond. This is a binary thing. He's either diamond or he's not.
When he's in diamond form, he is much stronger than his (well-trained strong human) norm, able to easily lift and move around 25 metric tons (27 US tons) and with effort, twice that. His zero-range TK power remains active allowing him to lift things that would otherwise break or bend. He's practically unbreakable in that form as well, requiring at least 300 tons of force to crack his flesh -- or a properly tuned vibrational attack.
While in diamond form, his mind is completely shielded from telepathic intrusion of any kind, though like his durability, his mind-wall can be breached by a sufficiently powerful assault from someone who is touching him.
His involuntary ESP abilities, including danger sense, are blocked, though he can still use his voluntary ESP with effort and concentration. Teleportation is unaffected by diamond form.
ESP
Jacky has Extrasensory Perception. Normally, it's under his voluntary control, when he can use it for touch- or sight-ranged perception, hearing or seeing at a distance, picking up psychometric information, picking up surface thoughts and emotions, seeing "through" solid objects (or usefully, fog) or even sensing illness or injury. He can also sense life-energy, metahuman or mutant power, magical energy, and whether a thing is alien to its environment. This all requires deliberate concentration.
However, he also has an involuntary reflex sometimes. It gives him a ten second danger sense (mostly if the danger is from someone with ill intent or is something that would injure him or someone near him - and this has included sensing the police closing in on someone). It can also give him unintentional waking ESP intrusions or break into his dreams. The intrusions in dreams are usually some sort of future-sight or a warning of something happening elsewhere that needs to be addressed. Intrusions while waking are usually due to something urgent and immediate.
TEKE
Jacky has "zero-range telekinesis" aka "touch teke" which scales with his physical strength. He has NO conscious control or awareness of it as a specific power, mistaking it for a part of his ESP. Not especially useful for large movements, it mostly permeates things and allows very fine manipulation of molecules.
SHIELD: this use of the power allows Jacky to instinctively protect someone from harm, or to reduce the effect of random projectiles, abrasions, etc. It generally kicks in only during an emergency or when his danger sense flips on.
HEALING: This power allows him to speed-heal himself in human form (he thinks it's simply meditation and bio-feedback) and when using his ESP to scan an animal or another person, he can sometimes reflexively help them to heal from injury or disease, or to ease a condition that's keeping it from recovering (like moving a kidney stone or breaking up bladder stones in a cat.) He has, once, desperately fixed his phone when he dropped it and was afraid he'd broken it. (He had, but a bit of molecular-level manipulation repaired the break.)
DIAMOND: When he's in diamond form, he can use it to repair cracks and breaks in his body, again thinking it's biofeedback to speed his normal healing. He doesn't HAVE normal healing in diamond form. He also uses it to lift things that he otherwise would have no ability to lift because of physics and the limitations of materials. The shielding effect can protect himself, things he's lifting, and other people, much more strongly than he can in flesh form.
TELEPATHY
Jacky has mid-range telepathic abilities. Like his ESP, he has voluntary and involuntary forms. He can voluntarily read thoughts, intentions, and emotions in line-of-sight or at a range of about 500 meters around himself, by lowering his mental barriers. His mental barriers are strong enough to keep out a Xavier-class telepath. He can attempt to "push" the thoughts, emotions, or actions of other people, usually only one or two, but if the emotional broadcast is simple, he can affect larger numbers. He's been known to use this during musical performances, as well as when scamming someone.
His power is strongest at touch range. If someone is touching his skin, they can get past his barriers more easily. The main exception to this is when he's in diamond form, which protects him from all but the strongest intrusions, and even those have to be done by touch.
TELEPORTATION
Jacky can teleport himself, others he's touching, or things he's touching short distances of a few hundred meters relatively easily, or up to ten kilometers to places he's currently aware of by ESP. The teleportation is somewhat tiring and he has to rest for a minute or so. He can teleport himself and others much longer distances if he's well acquainted with the area he's going to, but if it's much outside the usual range, it will drain him to exhaustion for several hours.
