Blissey is Slowbro's most well known and most splashable partner, with the two of them forming the rather infamous "BlissBro" core. Blissey's absurd special bulk lets it take on the strong special attackers than Slowbro hates dealing with such as Zapdos, Greninja, Mega Charizard Y, and Tapu Koko, among others. In exchange, Slowbro checks the physical attackers that can break through Blissey like Garchomp, Gliscor, Landorus, and Mega Medicham. However, the beauty of their partnership doesn't just stop there, as Blissey's access to Toxic gives it a way to cripple bulky Waters and Grasses that can pivot around this core (sans the likes of Pex and Amoonguss), or as an alternative, Thunder Wave helps to cripple stuff like CM Clef, Toxapex, Kartana, and Mega Scizor which prove annoying to both it and Slowbro.
However, even that isn't what makes Blissey Bro's best partner nor is it what makes the core so powerful. No, it is the fact that both members have access to Teleport, essentially letting them gain momentum on switches/pivots and using said momentum to either pivot into each other or even into a strong breaker. The fact that Blissey literally doubles Slowbro's pivoting potential and ability to gain defensive momentum for the team is what truly makes it Bro's best partner
