Black Racer - Marvel Comics

Continuing on with Marvel Comics seemingly endless supply of snake based characters, we have Black Racer.
She is not to be confused with Jack Kirby's Black Racer, a character in his "New Gods" pantheon.
Black Racer was created by Mark Gruenwald and Tom Morgan and first appeared in 1988 in Captain America #337.

This lady is Ariana Saddiqi, a mutant with superspeed.
Yeah that’s pretty much it.
Superspeed.
And she seems to be in the Quicksilver range, nothing like the Flash.
Well she does have some limited superstrength.
You would have to I guess, to be able to handle superspeed.

Of course since she is snake themed, she has been a member of both the Serpent Society and the Serpent Squad.

One odd thing about her is that her race changes.
She has been drawn as both Caucasian and African-American in different books (her green hair when she is in costume is a wig).
Judging from her last name, is it possible that she is actually Middle Eastern?
It looks like Marvel would get that together.

Black Mamba - Marvel Comics

Marvel Comic's Black Mamba.
Boy...Marvel really does love the snake-themed villains dont they?
Black Mamba was created by Mark Gruenwald and Ralph Macchio and first appeared back in 1980 in Marvel Two-in-One #64.
She is a bit more naughty than other supervillains...she was a call girl before she got a costume.

In the comics she was created by Roxxon Oil Company (yes, an oil company was an evil organization) and was a founding member of the Serpent Squad, which later changed it's name to the Serpent Society.

Now here is Mamba's rather unique power.
She can scan a person's mind and pick out a loved one.
Then she projects extra-dimensional Darkforce energy around the victim and it crushes them, all they while they think that they are being embraced by said loved one.
She can also use the Darkforce to surround herself and change her appearance.

Black Mamba was a founding member of BAD Girls, Inc., a founding member of Serpent Squad (Serpent Society) and also a member of the Femizons, the Masters of Evil, the Secret Avengers and the Women Warriors.
She does get around.
