i dont think its possible to make them shiny + specific nature + specific HP type and power but i will try, and how do you want it (all 3 ways are easy)?
EDIT: alright i found a combination, it has hidden power fire (70), shiny, timid, and has this IVs: HP 14, Attack 10, Defense 31, Speed 6, Sp.Attack 26, Sp.Defense 23. if thats alright i will finish making them.
EDIT 2: we will continue this over PM.
