#DCComics highly anticipated Arrowverse crossover finally aired on CW this week, bringing together the heroes of #Arrow, #TheFlash, #LegendsofTomorrow, and #Supergirl in order to take on the villainous, alien menace known as the Dominators.

While the cape and cowl crew will have their hands full during the four-episode event, the collection of DC's finest is filled with fearsome fighters and super-powered metahumans who shouldn't have too much of a problem saving the world again. That is their job, after all.

In honor of this jam-packed, TV event, we decided to rank the top 10 fighters who are set to appear in the must-see crossover. Check out our power rankings below.

10. Citizen Steel

A newbie to the Legends team, Citizen Steel still has some work to do if he truly wants to live up to the legacy of his grandfather and former Justice Society of America member Commander Steel. Although he may not have his grandfather's combat skills, Citizen Steel can turn his skin to metal and has super strength, so at least he won't be totally defenseless when the aliens attack.

9. Atom

Ray Palmer is more brains than brawns, but he's definitely a formidable hero when he puts on his famed Atom suit. Palmer has a bit more combat skills than his protege Citizen Steel, but still has a way to go before he's throwing bad guys around without a superpowered suit like Sara Lance or Oliver Queen.

8. Heatwave

The villain turned legend is quite the firebrand (pun intended) and has some sticky fingers. However, when it comes time for a fight, Heatwave always shows up ready.

7. Firestorm

By themselves, Professor Martin Stein and Jefferson Jackson don't really have that hero vibe. But together, the duo turns into the incredible Firestorm, complete with flying and matter transmutation abilities.

6. Spartan

Diggle! Oliver Queen's former bodyguard has turned into an awesome hero in his own right, even if his helmet needed an upgrade this season (thanks Cisco!). As an ex-soldier and seasoned vigilante, Spartan is total badass who should be able to clean a few alien clocks during the crossover, that is, if he doesn't faint from shock.

5. Vixen

The JSA stalwart turned unwilling Time Master is as smart as she is fierce. Vixen may be a hero out of her time, but her magical totem (which gives her amazing animal powers) should be able to keep her in the fight long enough to send the Dominators back to outer space.

4. White Canary

Since coming back from the dead, Sara Lance has been a woman on a mission, so don't think a few meddling aliens will be able to keep her down. White Canary may not have the trick arrows or powers like her collection of super friends, but as a former member of the League of Assassins, you definitely don't want to get on her bad side.

3. Flash

Barry Allen isn't much of a fighter without his powers, but when the Speed Force is flowing through him, there's few people who can stop him. After saving the multiverse and his timeline on multiple occasions, the Flash is well-deserving of a top three spot in the rankings of the Arrowverse's best heroes.

2. Green Arrow

What Oliver Queen lacks in superpowers, he certainly makes up for with his years of combat experience and training. Green Arrow has taken out quite a few metahumans by himself before (including the Flash), so he should be just fine when the alien invasion comes to town.

1. Supergirl

Supergirl may not be the most veteran member of this superhero squad, but she definitely packs a punch. Between the super strength, flying, and heat vision, the Last Daughter of Krypton is clearly the most powerful fighter in DC's TV crossover event.
