Unlike its fellow Poison Ultra Beast Naganadel,
Metroid Nihilego can't boost its Special Attack outside of Beast Boost. But what if it could? Acid Spray + Continental Crush allow Nihilego to muscle through some of the non-steel mons that check it, including Snorlax. An alternate spread of 36 HP / 44 Def / 172 SpA / 4 SpD / 252 Spe can be used to boost Speed instead, with the benefit of always living a Mega Metagross Bullet Punch from full, if you come across one after boosting.
252 SpA Nihilego Acid Spray vs. 252 HP / 4 SpD Snorlax: 33-39 (12.3 - 14.6%) -- possible 7HKO after Gluttony Figy Berry recovery
172 SpA Nihilego Acid Spray vs. 252 HP / 4 SpD Snorlax: 30-36 (11.2 - 13.4%) -- possible 8HKO after Gluttony Figy Berry recovery
252 SpA Nihilego Continental Crush (160 BP) vs. -2 252 HP / 4 SpD Snorlax: 247-292 (92.5 - 109.3%) -- 56.3% chance to OHKO
172 SpA Nihilego Continental Crush (160 BP) vs. -2 252 HP / 4 SpD Snorlax: 235-277 (88 - 103.7%) -- 25% chance to OHKO
