Supergirl: [SPOILER] Dons Iconic Super Suit

SPOILER WARNING: This article contains major spoilers for "For Good," the latest episode of Supergirl.

Lillian Luthor just got a serious upgrade. In "For Good," the latest episode of Supergirl, Lena's villainous mother returned to National City with a quest for revenge. The events of the episode led her to put on Lex's war suit, aka the Lexosuit, which was teased back in Season 2.

"For Good" ignited a new battle between Lena Luthor and Morgan Edge. The episode kicked off with a near-death experience for Edge. Someone seized control of his car remotely and sent it straight into the harbor. Considering their last confrontation, Edge immediately blamed Lena, who had nothing to do with it.

Though Lena asserted her innocence, Edge didn't buy it. In retaliation, he poisoned her coffee. The assassination attempt would have worked if Kara hadn't been there. Supergirl was able to save Lena by rushing her over to the DEO, where she teamed with Alex to save their friend's life. In the meantime, James tracked down her would-be assassin, only for him to be shot with a dissolving bullet.

Once she recovered, Lena was able to track down the origin of this dissolving bullet to an offshoot of LCorp. There, she discovered her mother Lillian, who wanted revenge on Edge for trying to harm her daughter. While Lena verbally sparred with Lillian, she noticed a drone and was able to piece together her mother's next move in her plot to kill Edge.

Knowing that her mother planned to kill Edge at his gala, Lena went there to head her off. She used the knowledge of her mother's assassination plot to extract the truth from him. As Lillian sicced her drones on him, he gave a hurried confession; Lena then removed his badge, which the drones had been targeting, thus saving him from certain death.

Lillian then arrived at the gala in person to express her disappointment that Lena would save Edge. Supergirl went to step in on Lena's behalf, only for Lillian to reveal her secret weapon: the Lexosuit, which is based on Lex Luthor's famous Kryptonite-laced exo-suit from the comics. Using the Lexosuit, Lillian engaged in hand-to-hand combat with the Girl of Steel. Supergirl was able to overcome Lillian and knock her out of her suit thanks to some help from Mon-El.

Though this is the first time we've seen the Lexosuit in action, it actually debuted back in Season 2. In a midseason episode, Lillian Luthor revealed a veritable treasure trove of weapons and other items of power reclaimed from LexCorp before Lena took over. The Lexosuit, as pictured below, was one of the items held in this facility.

Airing Mondays at 8 p.m. ET/PT on The CW, Supergirl stars Melissa Benoist as the Girl of Steel, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen, Chyler Leigh as Alex Danvers and Jeremy Jordan as Winn Schott, with appearances by Calista Flockhart as Cat Grant and Tyler Hoechlin as Superman.
