History
Zigzag was the dog of the Bakian Clan.[1] When Eve returned to her family and gave each of them Nova Stars, Fayne insisted to give Zigzag one of them. To Eve's surprise, the Nova Star worked perfectly on a dog.[2]
Zigzag proved ultimately vauable in finding the remaining Infinity Stone, using her enhanced smell to track down the Reality Stone so the Bakians could get it before Thanos.[3]
