I’d go cosmic w. it.
This one's all Marvel; i gotta think on a DC one maybe...:
Sensing a cataclysmic disturbance in the fabric of space/time, emanating from somewhere in the Shi’ar Empire, Galacta...
...has her Herald, Nova...
...recruit an expert on the Empire space sector, and undeniable powerhouse, Kid Gladiator...
...before going to investigate.
The three of them find the disturbance, which is worse than they'd feared; an incursion by Shuma Gorath itself. They throw themselves at the unthinkable, in whats surely a losing battle.
That battle catches the attention of a humble Poppuan, the Impossible Man...
...out for his morning jog across the galaxy after dropping his kids off at school.
As he very much wants to see his family again at the end of the day, Impy uses some outside the box thinking to locate and bring to the battle, the vaunted Space and Time Infinity stones...
...which are currently in the possession of the mighty Earth titan, Giganto.
Now five strong, w. two powerful macguffins, the good guys do the one thing they can against Shuma Gorath, which they have no actual chance of beating. They reverse its access point and banish it for like the 18th time in recent history.
The group then go their separate ways, agreeing to never speak of this again. Excelsior!
Went w. an X-Force vibe via DC. I always liked the original line up. Gender bent two characters, keeping the male/female ratio. Also kept to the age ranges.
DEADSHOT
Replaces Cable. Older team leader, would train the team in a cut throat fashion. Loves BFGs, has the funky eye thing going on.
BOMBSHELL
Replaces Boomer. Has the blowing stuff up angle more than covered.
WILDCAT II
Replaces Feral. The team’s cat character. Gender bent as mentioned.
SUPER CHIEF
Replaces Warpath. The New52 character is younger than previous versions, and fits the big strong Native American role.
THE RAY
Replaces Cannonball. Vastly different power sets but visually both characters are flyers w. distinctive energy coronas.
ROSE WILSON
Replaces Shatterstar. Sword wielding meta human badass. Gender bent as mentioned.
JINX
Replaces Domino. The second older character, someone Deadshot might have previously known and asked to help train the team. Very cool luck powers.
