Power Girl!

 is a superhero animated TV series, based on the DC Comics character of the same name, airing on HBO Max.

Premise
A young teenager named Karen Starr is given special superhero abilities after finding out she is the biological cousin of Superman, and becomes a new hero of National City named Power Girl.

Main

 * Kara Zor-L/Karen Starr/Power Girl (voiced by Aimee Carrero) - a teenager who finds out she is the biological cousin of Superman after learning she shares his Kryptonian powers, and uses them to become a superheroine.

Supporting

 * Kristen Wells (voiced by Colleen O'Shaughnessey) - a nerdy teenager who is Karen's best friend as she absolutely is fascinated by aliens, being fascinated by Power Girl.
 * Prof. Emil Hamilton (voiced by TBD) - a professor at Karen's school who in his own time studies aliens as he learns Karen is Power Girl and helps mentor her.
 * Ursa (voiced by Ashley Tisdale) - a Czarnian freedom fighter and explorer who survived Amalak's killing of their own kind. Along with the same powers and abilities of Lobo (such as superhuman strength and speed on par with Power Girl, hand-to-hand combat skills, regeneration, immortality and invulnerability), Ursa can also replicate herself, and wields the Lightning Siren, a guitar which she can also use as a hammer-like weapon, and flies across the galaxy in the Star Tiger, a space-travelling motorcycle resembling of a winged white tiger. Described as the opposite of Lobo by appearance and personality, Ursa is also more heroic and friendly towards other people (including superheroes), including Power Girl.
 * Kal-El/Clark Kent/Superman (voiced by George Newbern) - the main protector of Metropolis and Karen's cousin who occasionally visits her in National City, wanting to help her out at times.
 * Lobo (voiced by TBD) - a Czarnian bounty hunter who both clashes against and occasionally works with Superman as he gets involved with Power Girl while searching for the truth behind his planet’s destruction.

Antagonists

 * Amalak (voiced by TBD) - a space pirate who despises all Kryptonians with a passion as he arrives to National City, wanting to capture and destroy the last Kryptonians. It is revealed he also despised Czarnians and slaughtered all of them besides two.
 * Mr. Z (voiced by TBD) - a calm yet mysterious immortal crime lord who has his hands all over National City as he becomes fascinated by Power Girl.
