Beheeyem

Beheeyem is among the best Pokemon in PU as one of the more harrowing wallbreakers to face. Beheeyem's sky-high base 125 Special Attack mixed with Analytic means that it hits like a truck, cleanly OHKOing a significant portion of the tier and even 2HKOing some special walls. Beheeyem has three ways to leverage this power: a bulky setup set for stallbreaking, Choice Specs for immediate wallbreaking power, and Trick Room for sweeping late-game. However, none of this means that Beheeyem isn't without its counters. Walls like Scraggy and Bronzor can counter Beheeyem no matter the set, but other choices like Audino and Shiftry can reasonably counter it depending on the set.
