History: Tanya Sealy was selected by executives
in the Roxxon Oil Company to be a special agent in covert
operations. At the Mutagenics Laboratory of Roxxon's subsidiary,
the Brand Corporation, Sealy underwent an operation to
surgically implant a special component in her forebrain,
enabling her to tap her brain's energy in a unique way.
Her first field mission was joining the new Serpant Squad
in their attempt to retrieve the Serpent Crown. She remained
with the nucleus of the group when they went freelance.
Months later, she and her cohorts were invited to join
the Serpent Society, an organization of mercenary costumed
criminals. She readily accepted the invitation, savoring
the prospect of steady income.
Height: 5 ft. 7 in.
Weight: 115 lbs.
Strength Level: Black Mamba possesses the
normal human strength of a woman of her age, height, and
build who engages in moderate regular exercise.
Known Superhuman Powers: Black Mamba possesses
the ability to project an inky cloud of extradimensional
energy known as the Darkforce. This energy is manifested
by Black Mamba as a limited quantity of viscous semi-solid
matter. It is not known how far Black Mamba can project
this energy manifestation, but her control over it seems
limited by her line of sight. It is also not known how
much of it she can manipulate at once: so far she has
not been observed using it against more than one person
at a time. Black Mamba uses the Darkforce (a process she
refers to as "shedding her skin") to surround,
constrict, and suffocate her opponents. The maximum amount
of pressure she can generate through her Darkforce-projection
is not known. However, the superhumanly strong Thing seemed
unable to break its grip when he was encompassed by it.
Black Mamba also possesses some form of hypnotic
power, enabling her to mesmerize her opponents into perceiving
her Darkforce projection in the image of someone they
love or trust. It is not known how irresistible this ability
is, but the Thing, Iron Man, and Captain America have
proven susceptible to it. As part of the hypnotic illusion,
her opponent imagines him or herself in the embrace of
his or her self-chosen loved one, and the implausibility
of the loved one's sudden materialization and provocative
behavior is overwhelmed by the sensation of euphoria she
triggers in most human brains, if one remains in the grip
of her illusory Darkforce projection for too long, he
or she will succumb to suffocation. The amount of time
this takes varies according to the stamina and breath
control of her opponent. The victim dies, however, overwhelmed
by ecstasy. Black Mamba may need to be within line of
sight of her opponent not to direct the Darkforce, but
to use it in conjunction with her hypnotic power.
Limitations: Besides those limits to her
power described above, Black Mamba needs to concentrate
in order to project her "snake-skin." Also,
if her Darkforce projection is bombarded with certain
powerful energies she will feel the force of that disruption
against her body. This feedback effect may cause her pain
or the loss of consciousness.
