Nate's primary mutation is telepathy and telekinesis much like his mother, Jean Grey, and like his mother, that comes with A Whole Lot Of Other Things with both being such umbrella mutations. Given his current canon point, he hasn't yet mastered his abilities and, therefore, hasn't tapped into any real God-like potential just yet (reality warping, stepping in and out of time streams, astral travel, etc.) but is still relatively strong.
In terms of TELEPATHY, he's capable of reading or scanning minds, manipulating other's thoughts, communicating within the mind, mentally shield or cloak himself from others, create telepathic illusions, dream manipulation, mind links with others. These are typically the ones he'll display or use the most.
In terms of TELEKINESIS, he's capable of flight, creating force fields or "telekinetic bubbles", psi-blasts (think Cyclops but yellow), tactile telekinesis, moving things with his mind, etc. You know, usual telekinetic stuff.
π₯ Being Jean Grey's (alternate) son, a telepath, and omega level mutant to boot, Nate has the possibility of being a potential avatar of The Phoenix Force although he's never actually bonded with the creature before. There was a time (or two) he seemed to have the aura of it though, so. Who knows.
π Despite his power, Nate has his own weaknesses as well, the big two being his overconfidence in himself and when becoming too emotionally unstable. He tends to think he's stronger than others and can underestimate those with similar strengths (but more skilled) to his and when he loses control of his emotions/gets upset, he has the potential to lose control of his powers and lash out with them in ways he doesn't always mean. It also makes him easier to be manipulated when his defenses are down/he's emotionally unstable.
