History
Zet Krill was from an alien race from an unidentified planet. He and his parents went out to explore the galaxy in search of new planets to colonize. During their travels they encountered a distress signal and went to investigate. They discovered the signal was a trap by a Brood-Infested Acanti, and attempted to flee but their vessel was boarded. Zet, his sibling and mother were infected and transformed into Brood, his father Tyrus was similarily infected but was able to inject himself with a depressent which supressed the infection. Ulara then left in the escape pod.
Eventually Zet and her brood nest took root on Earth in the Hotel Ripley on Earth, bringing them up agains Wolverine and a venegeful Tyrus. After they managed to take out all the Brood, Krill left himself transform into a Brood, tricking Wolverine into killing him. As Krill lay dying he revealed the full truth to Wolverine, who laid Krill with his dying family. Wolverine returned their bodies to the ship and with Beast's help they returned the ship to their homeworld.[1]
