Hail!
It's finally come down to this. The monster responsible for the deaths of the first Iron Eagle and Spitfire is loose and has come to finish what he started. If he has his way, he would go after Sara, Sara's unborn child, Crystal, Andrea and the first Lady Liberty. Helping him on his quest, of course, is Dimitri. Dimitri is not quite right in the head at the moment. You can thank the Russian variant of the super-soldier serum he ingested for that.
The American variant gave Jack and his sisters some of their fantastic abilities. The sisters received high endurance and resistance to injury as well as Jack. The three of them also "blossomed" early as puberty was a trigger for the serum as I explained in the comic. It should be noted that when Sara and Crystal eventually joined the Starbolts, no one noticed any super-soldier-like tendencies until the great reveal that they were the twin daughters of Stan and Andrea Whitefox.
Of course Clive Marshall was giddy at the prospect of getting two super-soldiers in the employ of Terra Nova. That's why he experimented on the both of them. He wasn't about to miss his chance to really examine what made the girls tick. At least he's in jail now along with the rest of Terra Nova's inner circle. There's still much the Starbolts have to clean in the wake of Terra Nova's dissolution. That green guy is definitely one of them as he did kill the three Whitefoxes' grandparents.
Jack is now face to face with their killer. It's up to him to stop him before he kills again.
Now that we know what all three Whitefoxes inherited from their mother. What have they inherited from their father, the world's greatest sorcerer? Stay tuned and find out!
