User blog comment:T-Drag/Kuma's DF is cheap?/@comment-3119203-20110217134915/@comment-3242083-20110217141039

Fortunately for us, his ability leaves no room for speculation. He states himself that he is able to repel everything he touches and even proofed it by repelling pain (!!?), as well as Perona's untouchable ghosts. I said it in the past and I will do so again, the Nikyu Nikyu no Mi is easily in the top 5 of all known fruits (so far).

Super overpowered, but since Kuma is not able to use it properly now it doesn't matter anyway.
