Thor is the 3rd edition to the pack. Altho he was not one of Mew's baby's, she accepted and looked out for him ash he was her own. Mew and Thor have become very good friends over the years often running together in a pack. altho Tabs is Mews Blood Son you would never be able to tell because of the relationship she holds with little Thor. Thor has multiple owners around the complex but only sleeps in one spot every night. His name Varys from Thor to Buttercup to Turbo to Creamsicle, Shithead, Hey You, Get Out Of Here, Simba, Little Foot,  Short Round...the names keep on going as He has lost count at this point.
