Chansey

Just like Blissey in OU, with great Special Defense, enormous HP, and instant recovery in Soft-Boiled, Chansey remains the dominant special wall in UU. Access to both Wish and Aromatherapy to keep her teammates healthy also makes Chansey a very important member on stall teams. Unfortunately, Chansey's utility comes to a halt after that; holding the title of the lowest Defense stat in the game, she will crumble to almost any physical attack. Seismic Toss is also Chansey's only viable option of dealing direct damage, which means she is easily shut down by Taunt users, Ghost-types, RestTalkers, and setup sweepers. Even with these glaring issues, Chansey still consistently fulfills her job as a fantastic team player and full stop to most special attackers, cementing her position as one of the most frustrating defensive threats to face.
