It was bad for the delay, but now I can respond
From what I read from Mob's page on Absorption, I do not think he would be able to stop Zahard from using shinsoo in ToG, shinsoo is everywhere, regardless of location, he would have to absorb the shinsoo of the entire HF so Zahard would be incapable to use shinsoo, and from what I see about the range of Shigeo, he will not, I think
So Fear Manipulation is not going to be anything for Mob
Well, due to being a data, Zahard is able to regenerate automatically after being injured manipulating the data world to heal/regenerate himself, even when his body is totally destroyed he will generate a new one and immortality (Type 8) is due to his nature as a data human and being connected to the Hidden Floor, I mean, Mob would have to totally destroy a Hidden Floor, which is twice as big as the North American continent
An addition on the Zahard regen, it can only be denied via Information Manipulation, since even Baam who possessed, Regen Negation (up to Low-Mid), was not able to deny his regen until gaining Information Manipulation
