Supergirl Season 3 Trailer Reveals First Look At Newest Villain

A new trailer for Supergirl Season 3 has surfaced, and fans are getting their first look at the newest Arrow-verse villain Bloodsport. Catch some quick glimpses of Robert DuBois in the trailer below, and continue on to learn how he'll be a thorn in the side of Kara this season:

While new to the Arrow-verse, the character of Robert DuBois has a long past in the DC lore. Making his debut on Supergirl, DuBois has historically been an enemy of her cousin Superman. Armed with the ability to summon high-tech weaponry from a remote location, not to mention a gun that fires Kryptonite bullets, DuBois was often a thorn in the side of Superman whenever they crossed paths. It looks as though he'll cause the same issues for Kara, although it's not immediately clear how much of his character's comic history will travel with him to National City.

In the comics, Robert DuBois was a Vietnam draft dodger who fled to Canada when his name came up to serve. His brother Mickey would take his place in battle, only to lose all of his limbs overseas. Riddled with guilt over what happened, DuBois suffered from mental illness and was sent from hospital to hospital before being discovered by Lex Luthor, who gave him all his fancy tech to destroy Superman.

This all appears in line with a character description that came out a couple months back that portrayed DuBois as an ex-military man who invades his former base and steals weapons. DuBois then use that weaponry and technology to cloak a nuclear device, which he intends to detonate in the National City waterfront. Without getting too heavy into potential spoilers, let's just say that Robert DuBois isn't being bankrolled by Lex Luthor, but another major player in town in Supergirl Season 3. Everything but the last bit appears to be teased in the trailer, so it's safe to say this sounds like the most accurate description we'll get of Robert DuBois before we see him on screen.

As threatening as Robert DuBois sounds, Supergirl almost seems even more threatening. The cool confidence, showcased in her"I got this," attitude, is a good look for Kara, and definitely a sign she's embracing the Supergirl persona over being Kara Danvers. Hopefully that overconfidence doesn't work against her as nuclear destruction near a major city is never something to to be so casual about. Then again, Kara's fought off an alien invasion, so one can't blame her for being just a little cocky.

Supergirl will return to The CW for Season 3 on October 9th at 8:00 p.m. ET. For a look at when all The CW shows are scheduled to premiere feel free to check out this helpful article breaking it all down. For a look at all new television appearing this fall, visit our fall premiere guide.
