I have the onyxia hatchling on only like 1 character per server, i play on about 4.. I never deleted them and they used to be in my bank, Why don't we get them in the mail every time we create an alt like the rest of the pets? I think the baby blizzard bear is also mailed on character creation.
It was a pet rewarded to any characters that logged on during the 5th year anniversary. While some special pets are account-wide and mailed on new character creation, the Onyxian Whelpling was not one of them.
