1) Having planted a device on Earth during the last Invasion, the Dominators activate it, using it to bypass any of Earth’s early warning system and defenses, launching a new invasion that takes everyone complete by surprise and allows them key offensive positions around the globe.
2) Various battles against the alien invaders around the world by the various groups and individuals. These can be won or lost depending upon consensus within the groups. I’d like to possibly think of each of these as a mini-plot. Victories here are actually to be expected and wanted, though losses of various types (stop the main threat, but fail to prevent the theft, or even outright failure) work too.
These are only examples/suggestions and can be modified as necessary.
a) JSA vs. Khunds in Washington, DC.
b) Teen Titans vs. the Gil Dishpan in Atlantis.
c) Shadowback vs. Gemworld natives in England
d) Titans East vs. the Reach in Egypt
e) Doom Patrol repels a Coluan attack on Cadmus
f) Outsiders vs. Man-Hawks attempting to steal a nuclear arsenal
g) Suicide Squad vs. Predators (they’ve fought Superman, Batman, and the JLA. They’re part of DC continuity) in the South American jungle
h) BoP vs. Sklarkan (DC’s stock female space pirate race) doing tech thefts in Gotham
i) YJLA vs. Vega-System races in Metropolis
j) Individuals and other team-ups across the globe as wanted
k) Possible scenes with the villains fighting back too.
3) Meanwhile, the Darkstars liberate prisoners from a Dominator laboratory world and discover news of the invasion. They race off to Earth.
4) A group of heavy hitters of the heroes (Jon Kent, J’anna, the Lanterns, Fate, Firestorm, etc) go after the Dominator fleet in orbit around the planet. The other heroes on Earth keep up the fight against the remaining forces.
a) In the middle of the fight, the Darkstars arrive to assist with Aleron, Katima, and Mari joining the fight in space and Cyrus and Aleea running support from the ship.
b) This seems to be going entirely too well, until…
5) The Dominators sacrifice one of their own ships, detonating it and their new Gene Bomb. Being too close to the explosion, the heavy hitters are taken out and are captured.
a) Less erratic than the last Gene Bomb, instead of making powers go haywire, this one simply suppresses Metahuman ability, leaving only those with alien genetics (Varon, any of the Kryptonians, Jenn, Hope, etc.), magical abilities (the Shadowpact, Lily, the Hawk-Dove types), cybernetics (Traya, technically), or equipment users (Dinah and Riley, for example) as “powered.”
b) The Dominators pull out, but leave the other invaders behind.
6) Aleea and Cyrus gather up some of the remaining heroes (I’m thinking Batman, the Hawks, etc) to stage an attack on the Dominators homeworld, breaking into their primary lab to free the prisoners. With the heavy hitters back on their side, they force the Dominators into giving them the antidote to the Gene Bomb.
a) On Earth, the remaining heroes, “powered” and “depowered” have various fights which lead to the defeat of the rest of the invaders, with the help of Earth’s military, the remaining “powered” villains, etc.
7) The space group returns and uses the antidote.
