I bought a pet these days in AP ...
I took it with my char and uzei.
so I decided to do another and wanted the pet in another char
So it has nothing that can be done to send to my other char?
If you are referring to the 69 AP deal with the Free pet, that is a 1 per account limit deal
. So you won't be able to buy more of this deal if you have already purchased it.
However if you want a derpy pet for your other character, you can buy one in the Boutique section, under the pet tab here.
They cost more AP, but they are also not tradable. So once you redeem it on the character you want, you can't trade it.
Hope this helps.
