Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Not just legends I can RNG Roamers, eggs, wild Pokemon like this Kadabra I accidentally RNG'ed while trying to get Mewtwo. Yeah It had Mewtwo's IVs but I couldn't save with it cuz I already caught Mewtwo and before I caught Mewtwo I didn't know it was flawless until I saw Mewtwo's IVs.
