Uncertain Origins

The original roster of the team appeared to be Vox, Prima Donna, and Frog Man.  At some point Frog Man had been replaced by a Skrull as part of the Secret Invasion; this could have been before the team was even formed, or it could have been later.  

Creation

Action Pack was created by Dan Slott and Stefano Caselli in 2007 and first appeared in Avengers: The Initiative # 7. 

Secret Invasion

Once the fighting of Secret Invasion (an attempted Skrull takeover of Earth) began, the Skrull Kill Krew was teleported to Action Pack base by Devil-Slayer.  Through his special glasses, Krew member 3-D Man saw that the thing everyone thought was Frog Man was really a Skrull.  The Krew instantly killed the alien.  Vox and Prima Donna then went to Times Square where they assisted in the fight against the Skrulls.  The battle moved to Central Park and Earth's forces one.  It is unlikely either died in the fighting.  
The real Frog Man was found captured in a Skrull spaceship; he took therapy and readjustment classes.  It has not yet been shown how long he was gone for and thus it is not a certain fact that he (re?)joined Action Pack.
