In my sig. :) I just need to know which to use for you, B or B2.
I did confirm, it's a Mild nature Pichu. The other three in there are males.
As for cloning, I clone Events as well. Think of it; the system giving them out doesn't have 1,000,000 Pokémon on it, it creates a clone of the Event every time. Thus, every Event as received is a clone. ;) I may also make exceptions for Shinies, such as giving myself a few Shiny Eevees so I can get every Shiny Eeveelution for myself (and maybe offer them in my trade shop someday as well, noting they are clones).
But yes, this is NOT a cloned Pichu, it's a hatched one and only one like it, and holding a Thunderstone in my party right now so it's quick to get to. :)
