The team codenamed Blackjack works for the organization known as G.R.A.M.P.A.
and consists of two highly capable field agents, Ace
and One-Eyed Jacquie
. Without any help from outside agencies, Blackjack has successfully defended the Earth against domestic menaces like King Simian
to threats of cosmic proportions such as Terminus. They have also fought alongside Henry Pym and his team of Avengers
and made them temporary agents of their organization. When the time came to sever ties, Blackjack went to the Infinite Avengers Mansion just as the villainous Ultron
made his return. Unable to escape, Blackjack had no choice but to help Pym defeat the evil robot.
