Black Canary's sister, Sin Lance, undergoes a transformative journey that grants her superhuman abilities after receiving a divine blessing from a powerful god. Sin's body is taken over by the god, allowing them to unlock extraordinary powers and enhance their existing capabilities. This extraordinary transformation reshapes the concept of "godhood" in the DC Universe, elevating Sin Lance to a whole new level of superhuman prowess.

Black Canary's sister, Sin Lance, transforms into a super-powered hero by sharing her body with a powerful god. She gains the god's incredible strength, agility, and other abilities, allowing her to perform feats previously impossible for her. This extraordinary transformation reflects the boundless potential of the DC Universe, where ordinary individuals can achieve extraordinary feats through the magic and cosmic forces at their disposal.
Sin officially receives her new powers and costume in Birds of Prey #6 by Kelly Thompson and Leonardo Romero. As the conclusion of the revamped title's first arc, in which Black Canary forms a new squad to save her sister from a threat on Themyscira, Sin became a target of the god Megaera, who sought to steal her body to unleash the DC equivalent of Ragnarök.
Thanks to an unexpected bargain, Megaera and Sin agree to share a body, gifting DC a new hero with a Shazam-esque twist. As proven by Wonder Woman's lasso of truth, Sin will be in control of their body, but Megaera will share her powers, giving Sin a unique green-and-black costume to enhance her superhero persona.
In the series' first issue, Black Canary assembles the Birds of Prey with a singular purpose: to save her sister. Through the whispers of a future version of Maps — a Gotham Academy fan-favorite turned time-traveler — Dinah receives an unsettling message from her sister, warning of a dangerous fate that could befall her. Despite the team's valiant efforts, they achieve nothing, as Megaera's love for Sin proves too potent for her to resist completely. However, Sin, unwilling to succumb to Megaera's seductive offers, chooses a tragic fate rather than allowing him to utilize her body for his own destructive purposes.
Beyond the Birds' seconds ticking away, a delicate balance is struck. Megaera recognizes Sin's unwavering determination to ensure both their deaths, so a mutually beneficial agreement is reached. Megaera will inhabit Sin's body, granting her superhuman prowess, while Sin retains complete control over her actions. This amalgamation fosters a harmonious fusion, where Sin's divine presence is intertwined with Megaera's formidable capabilities, without triggering the catastrophic consequences that would accompany a direct clash between the two.
On one hand, the word of a god who just spent the last couple of issues wiping out Amazons is shrouded in mystery, something Wonder Woman is surely aware of. However, Sin's power boost gives readers a new and intriguing perspective on "godhood" in the DC Universe. The Shazam family showcases how a human can handle being bestowed the shared power of the gods, but Sin Lance's unique situation allows her to tap into the source of her power directly.
