The Supermen of multiple universes have banded together to impose their will upon all earths and create a new world order:
Superman
Sentry
Supreme (original)
Gladiator
King Hyperion
Supreme Power Hyperion
Blue Marvel (Adam)
Captain Marvel
Black Adam
Count Nefaria
Mr Majestic
Icon
Samaritan
Mon-El (has serum)
But there are those brave few who will try to stand against them. How far can the Supermen go before they would be stopped, if they can be stopped at all? All battles are fought separately, with no prep:
1) Supergirl, Maxima, Suprema
Gladiator's girl cousin from Starmasters,
Power Princess, Supreme Power Zarda,
Wonder Woman (lasso & bracelets only),
Mary Marvel (classic), Mary Marvel (black Mary)
Power Girl, Big Barda, Donna Troy, Isis, Andromeda
2) Juggernaut, Kurse, Konvict, Lobo, Ulik, Bizarro, Mongul,
Doomsday (DOS - if they kill him once he is out of the fight),
Dumb Drax (no PG), Savage Hulk, Abomination, Wendigo,
Pagan
3) Green Lantern (Hal), Dr Strange (Current), Firestorm (classic), Flash (current), Professor X, Vision, Quasar (WV), Ghost Rider (current), Invisible Woman, Captain Atom, Namor, Wonder Man (most powerful phase), Wolverine
4) Silver Surfer, Morg (WOL), Terrax, Firelord, Fallen One, Nova (herald), Stardust, Red Shift, Invisible Man, Ion (current)
5) C.A.P. Robot (Conserve and Protect), Reed Richards in Fully powered Anti-Galactus suit, the Destroyer (Loki's spirit), Amazo (powered by the 'Big 7' JLA only)
...
...
6) And if they can take that lot, then this legion of Supermen unwittingly enter the Marvel Zombie universe looking for new worlds to conquer. It is inhabited by all the zombies depicted so far (no cosmic powers). Do they get out alive?
The heralds and Ion are slightly outnumbered here but I figured WOL Morg counted for a few heralds to make it up. But I'm not quite sure if he could win the day for the herald team or not.
The Superman team should be able go through team 1-3. The only problem is Xavier, Maxima(i think), and Dr.Strange.
They wont be defeating team 4.
I don't know about the rest
