History
Darren Cross was first seen during Cassie Lang's science fair where he attacked Ant-Man and prevented him from helping fix Cassie's project. After flying through the science fair and escaping an angry hamster, they both landed on top of Cassie's volcano project and just as Darren leaped across the volcano to grab Ant Man, Scott threw baking soda and a growth disk into the volcano to encase Yellowjacket in the baking soda/vinegar substance.[1]
Darren later attempted to beat Ant-Man in retrieving Hank Pym's Proton Cube on behalf of the Masters of Evil. The proton cube caused time to slow down the battle. After Darren caught the proton cube and was able to flee, Scott was able to malfunction the growing process of Darren and cause him to freeze in place. Hank then used Darren as a coat rack and left him frozen in his office.[2]
