    This thread is dedicated to anyone else on the hunt for a Shiny/Max IV Mewtwo and also to confirm the facts that I have discovered/calculated. In some cases I will need some confirmation, but I am fairly certain, due to my academic background in Mathematics (Senior High-School Teacher).

    First of all, I am assuming the rate of finding a shiny Pokemon is the same as in previous series; 1/8192. I am also assuming that Mewtwo is not shiny locked (need confirmation). Finally, all of my calculations are based on a Modest Mewtwo as I am using a Modest synchronizer and am simply ignoring any other natures in my search (but not in my Maths below).

    After many soft resets, I have determined the following are the possible Max IVs for a Modest Mewtwo:

    HP: 250
    Attack: 162
    Defense: 152
    Sp. Attack: 266
    Sp. Defense: 152
    Speed: 208

    Since in Generation VI, Legendaries are given 3 guaranteed max IVs, the chance of getting Max IVs is as follows:

    P(3 Max IVs of your choice) = (3/6)*(2/5)*(1/4) = 0.05 = 5% = 1/20

    Given that any 3 are guaranteed to be at Max, this makes the following calculations:

    P(Any 4 Max IV) = 1/32
    P(Any 5 Max IV) = (1/32)*(1/32) = 1/1024
    P(Any 6 Max IV) = (1/32)*(1/32)*(1/32) = 1/32768

    Keep in mind that since I am looking for a Modest Mewtwo in particular, which is only a 50% chance due to synchronizer, the above rates need to be doubled. This means that the chance of getting a Max IV Mewtwo, that is Modest, is now 1/65,536 ignoring the insignificant probability of getting a Modest nature due to random chance (not synchronize effect).

    In all honesty, if I were to settle for a Modest Mewtwo that had 31 in everything BUT Attack (since I won't be using it and it is decreased due to Modest anyway), that would only be 1/12,288 (1/1024 * 1/6 * 2) rate which is decent in my opinion. I would still have a random IV from 0-32 for it, so that would be good enough for me.

    I will almost certainly find the Shiny Mewtwo first which I will snatch and keep, but I don't even know for sure if it's Shiny locked or not. The quicker the confirmation, the better!

    I will update this post with the best Mewtwo I have found so far. I am not settling for anything less than Modest 31/x/31/31/31/31, or a Shiny.

    Previous Best Finds:
    Modest - 250/162/152/264/151/205 = 31/31/31/29/30/28 (Rejected)
    Modest - 250/162/148/266/148/208 = 31/31/27/31/27/31 (Rejected)
    Modest - 250/159/152/266/152/205 = 31/28/31/31/31/28 (Rejected)
    Modest - 250/146/151/266/152/208 = 31/15/30/31/31/31 (Rejected)

    Current Best:
    Modest - 250/162/152/266/147/208 = 31/31/31/31/26/31 (Rejected)
    I'm totally gonna regret not settling for this, aren't I?

    THE SEARCH IS OVER:

    SETTLED FOR: 250/162/152/266/152/207 = 31/31/31/31/31/30
    I know I wouldn't settle for less so I am a tiny bit disappointed for not keep true to my goal but I couldn't let it go. I might for a perfect/shiny Zygarde or Moltres at a later date.

    Since Mewtwo is not shiny locked in previous generations, I would not think it is locked in this generation. I have heard of someone getting a shiny Mewtwo, whether that is fact or not I'm not quite sure.

    But my question is whether you intend to catch every Mewtwo you encounter to check for its IVs. I mean SR encountering is quite tedious in itself, having to capture every encounter and check its stats does seem infinitely more tedious.
     
    Yes, I am. To make it worse, my Kirlia gains 2 levels each time as well, haha.
     
    It has only been about 3 days and I'm getting over it xD
     
    I can feel your pain bro. I've done this thing for Yvetal and it took me 3 days to get the best Yvetal. Here's my best Yvetal. 30/30/31/31/31/31.
    I wish it has 5 perfect IVs but I just can't bear the pain of doing this thing day and night. Maybe a months later I might be hunting for a perfect Mewtwo/Moltres.
     
    Just rejected a near perfect Mewtwo, hope I don't regret it =s
     
    I understand your pain. I would have done this for Yveltal if not for the fact of having to catch it for the story and not being able to find an IV calculator to check each one. I ended up with 0/?/31/?/31/31.

    It is Timid but still horribly disappointing.
     
    Settled, see original post for details.
     
    Can anyone Confirm Shiny Mewtwo? I've never had a shiny (ever) and now that I'm more learned about the games, I'd like my first to be Mewtwo.

    Would love a confirmation. Right now I'm trying.
     
    Regarding the possibilites of shiny legendaries in X/Y, as far as I'm concerned, all stationary legendaries can't be shiny.
     
    Should I settle for a shiny Impish Mewtwo or a regular Modest Mewtwo?

    Sorry, but we're not allowed to revive dead threads (ones that haven't any posts in over a month), guys. Unfortunately, it's against the forum rules. :( Please be more careful next time before posting.

    Thread locked.
