I do not understand why people refer to the Pokemon anime when it has been shown that there are multiple legendaries of the same species (see baby Lugia) and they can also be caught by trainers (Tobias with Latios and Darkrai, Nurse Joy with Latias, frontier brains with Regis and Articuno), so that thought about them being unique and/or uncatchable is not true. Anyway, I'm happy PRO gives us a chance on getting legendaries, thanks for that, but I think we could have a better requirement than this "X number of hours played.".

Do you know if that Machamp had the Guts ability? If that's the case, Guts ignores attack reduction from burns and increases the attack instead. Well, that's how it should work, I don't know for sure if Guts is working as intended in PRO. From Serebii: "Attack is increased by 50% when induced with a status (BURN, PARALYZE, SLEEP, POISON, FREEZE). Burn’s effect of lowering Attack is not applied."
