Barry is a miniature version of Araxxor that can be unlocked as a pet from an Araxyte egg, which is obtained as a drop from killing Araxxi. The odds of receiving this item are 1 in 500 with a threshold of 200 (explanation of drop mechanics). After the item is used, Barry can be summoned from the pets tab in the hero interface. Unlocking this pet completes the Barry achievement.
