Sorry, DNA, i forgot about trading Pokémon with you.
Now, i've got my computer back and cloned my Pokémon right away. So i can provide more exact information:
Landorus has 31 IV in all stats, no effort values and is jolly in nature instead of adamant.
Haxorus has it's German species name, Maxax, has 251 EV in Attack, 255 in Speed, is also jolly in nature and has got the following IV: 31/31/26/21/31/31 (Speed comes last.)
By the way, if you got a shiny Mijumaru/Futachimaru/Daikenki, please let me know. I will join the chat soon, for further discussion.
