Here's his description of his concept and explanation of this piece I drew for him...
"When Marvel Girl, the maybe future daughter of Sue Storm and Dr. Doom, travels back to our time to avert a horrible disaster, she gathers together the only heroes strong enough to save the multiverse:
X-23 - Laura Kinney, female clone of Wolverine with healing factor and adamantium claws.
Hope Summers - mutant mimic who grew up in an apocalyptic future as Cable's daughter.
Lyra - the Savage She-Hulk from an alternate future, daughter of the Hulk and Thundra.
Hawkeye - Kate Bishop, young Avenger and protege of her namesake.
Troll - Gunna Sijurvald, daughter of a Troll and an Asgardian.
Mania - Andi Benton, bonded with the Venom symbiote when the current Venom used the symbiote to save her life.
Can these 7 teen girls really save all of existence? Or will they run out of time??"
(Time travel is one of the themes of the book)
Notice we have an FF type (time traveler/adventurer), a Wolverine type (fighter), a Cable type (leader/weapons expert), a Hulk (strength), an archer/Avenger, a Thor type (strength plus outsider), and a Spider. But no goody two shoes heroes (no Spider-Girl, American Dream, Lightspeed, etc etc).
These chicks are all bad ass (except Marvel Girl, the anomaly who gathers them together).
The costumes are all different colors, too, so it works visually.
X-23, Hawkeye and Hope Summers were all featured in previous titles, and Lyra had a miniseries, so there's some popularity to work with.
Marvel launched two titles with all female teams (X-Men and Defenders), so why not an all girls teen comic?
Variant Cover - I wanted to show them all badass and cool, and I remembered Marvel once had a cover where all the heroes smoked cigars. I thought that was cool because they're doing something that's frowned upon by society. So what can the girls do that's socially unacceptable? Teen Mom is popular on TV, even though teen pregnancy is seen as a big problem. So let's give them all babies! Why not? Marvel gave Jubilee one ('cept these little tykes are all natural, not found lying around somewhere), and they do enough 'Marvel Babies' variant covers. Where do they think babies come from?
So it's social commentary and comic book commentary, plus a cool, funny cover. It's a variant cover. In Teen Force the series, they wouldn't have babies. Although it would be priceless if Troll had a baby. She'd breastfeed it in front of everyone!
