Black Panther was once the defender of Hell's Kitchen

SUPER long story short:

T'Challa had to destroy all vibranium to stop Doctor Doom. Then he left the throne to his sister. Needing to do some soul searching after having lost everything, he decided to be Daredevil's replacement since Matt had to recover from being the leader of the Hand ninjas and being processed by a demon

Foggy assisted him in forging a new identity as Okonkwo, an immigrant from Congo and manager of the restaurant Devil's Kitchen.

Dr Sivana's sexy wife Venus

Sivana has four children. Venus is mother to Magnificus and Beautia.

Venus is actually Sivana's ex-wife, she divorced him after he became obsessed with Captain Marvel. But she loves him for some strange reason and even donated millions of dollars to a children's hospital in Kandaq so Black Adam would help find her missing ex-husband who had been kidnapped

She is awful and vane, treats her ugly step children with lack of love and respect and is even a racist, referring to Arabic as "speaking camel jockey"

I suppose she makes the perfect wife to the definition of evil scientist

Makes it even more insane that her daughter Beautia is practically a saint

Joker once beat Ras Al Ghul in chess

Joker claims that he is brilliant at board games since there is not much else to do in Arkham

Ras compliment Joker on playing so unpredictably that it is impossible to outsmart him

Lex Luthor had an Amazon as bodyguard

Originally a character from the animated Superman series, Mercy Grave was introduced to comics when Lex became president(yep, that actually happened). She was one of Lex's two bodyguards, the other being Hope Taya

They were both Amazons. Sure, they didn't have Wonder Woman's powers, but they had the same combat training from the paradise island

After Lex was kicked out of the White House, Mercy stayed with Lex, helping him rebuild Lex Corp

Btw, Hope apparently had SOME morality as she turned on Lex when he was president

That did not end well for her :/

Penguin was once part of the Suicide Squad

Waller made him part of a mission to rescue an author in Russia who had done nothing but speak her mind. Cobblepot was selected due to his expertise in robberies and could plan the rescue mission the same way he would plan a heist. He was forced to be part of the mission as well to motivate him into planning the mission properly so he could save his own skin

He didn't stay long on the team since the Russian mission was enough to get him out of jail
