What is the Strongest Pokemon in Pokemon Unite

you just pay money from in the game, there is no other way

It really depends on what you consider "strongest".

1. Just strength as durability? (Probably Slowbro even thought they nerfed him 3 times now and still is a tank!)
2. Strongest attack? (Single attack might actually be Vinasur cannon blast. I'm pretty sure it's the biggest damage with 1 hit. Not combo or anything like that im talking about 1 single hit.)
3. All time? Arguably Gangar or Mewtwo. These 2 when released or boosted became so broken it almost became an auto win with them on the team. I think mewtwo lasted a little longer but gangar nonstop moveset would almost guarantee a kill once he had you.
4. Currently over all best? Not really sure there is one. Kind of like rock paper scissors. All have some kind of weakness. And since they adjust pokemon like every update it's hard to say.
