ich klau mal aus einen anderen Forum hier wird das ganz gut erklärt
"Kabuto's ability is "Menace", a Visions ability. Just like Shiner, Kabuto can see "Impending Death".
Page 1
Notice how the author refers to "Impending Death" as "Ominous Lights". In this page you can see the "Ominous Light" clearly in the second panel. That is impending death.

And here we see it again even clearer than before.

So now that we have a better understanding of Kabuto's ability we can figure out what just happened with that Coin/Card wannabe clown dude.
Yoyo is practically a part of Kabuto's personality residing within him. Rather... a manifestation of his Psi, invisible to everyone else but Kabuto himself. In this page you can clearly see the "Ominous Light" of "Impending Death".

In the same page you can see Yoyo altering the course of this "Ominous Light". To the clown dude it seemed like Telekinesis cause he thought that Kabuto flipped him around, but in reality what Kabuto did was flip the "Impending Death" around. So my opinion is that while Kabuto's ability is to see Impending Death, Yoyo's abilty is to purify it.. in other words reduce its threat to nothing. It resembles telekinesis but it's cast on death, which noone but a menace user can do.
So now your question may be.. "Why is it that it's only the weak that become invincible with menace?" Simply because Menace can see only "Impending Death". If something were to damage Kabuto he would not be able to see it, but since Kabuto is weak even the smallest attacks in the psi world can kill him. Therefore not the slightest amount of damage can harm him cause he can see it all coming. Thus he is invincible."
