He has the potential to be one of the most powerful DF users if not for his Pacificista modifications. The Nikyu Nikyu has the power to REPEL everything, from people down to feelings as well. The power is as you said limitless and who knows what else it can do. Unfortunately, with Kuma's human mind erased, we'll never know for sure...

PS - I'd imagine Blackbeard and his crew wanting to go after this particular ability. If they got hold of it, God help us all...
