It can only be blocked by attacks of a similar nature (such as EI-15's fake Hell & Heaven, GaoFighGar's Hell and Heaven, and Palparepa PLUS's God and Devil). There is one notable exception to this rule - Zonuda's Barrier System was so impregnable that it was able to deflect Hell & Heaven with just its palms. In addition, while ZX-01's Primeval Object form was damaged by Hell & Heaven, it was too large to actually defeat with the move, and managed to counter with its fist form. Generally speaking, the success or failure of the move is invariably telegraphed by whether or not the enemy is properly bound by the tornado first, specifically in cases where the opponent is immune to some extent, and also taking into consideration their origin as another factor.
