During their invasion of America, the Liberators fail to take Wasp into account, discounting her as being no threat due to her abilities being those to make herself "smaller and weaker". Janet is able to make her way to the cells in the Triskelion where Captain America is being held under suspicion of the murder of Hawkeye's entire family. Though she is discovered and apparently subdued, she has already liberated her boyfriend. Though Captain America easily beats the , he stops fighting when several super soldiers threaten to tear Wasp apart; she then surprises them all by using her stinging powers at her normal size for the first time, killing or incapacitating all the super soldiers at once. At some point, Hank gives Janet a dose of the Giant-Man serum, which allows her to grow to gigantic proportions. At a larger size, Janet helps turn the tide in favor of American forces and crushes the Insect Queen with one stomp of her foot. It is unknown whether she can grow at will or whether this is a one-off experience.
