yup, a Martian, looking alot like Marvin, and her real form resembles a Xenomorph. I love aliens.

I wasn't origionally going to make this reff so soon since, well she first apears durring the first Justice guardians storyline (BTW, spoilers for the storyline are in her backstory) but well since I'm working on something on furaffinity, I thought, screw it.

Bio:
Name: Marvinia %#@&@ (last name unprouncable by non-martians)
age: physicly due to being frozen via gas, 15, though a best estiment is over 1000 years Earth time.
backstory: the last of her kind of once peaceful martians, marvinia was a soilder in an age old war with a race of aliens conqurors known as the horde, in the last fight, a gas was used , intending to kill them, but it only had the effect of freezing the horde, with Marvinia also effected, 2055, humans make it's hostoric first landing on mars, and apon discovering a hidden pathway, awakened the horde, andher aswell. although she did manage to escape to Earth (which she learned was the next target of the horde) the horde followed her, beaten her, and kepted her in a maximun security center for 3 years

durring these 3 years, all she had was very limited strengh in her mental abilities and a television, which she used to view the outside world, and also the heroes present, trying to contact them, she could only give brief messages, often credited as a brief migrain, even then only towards 2 people, Batboy, and Valient. eventually the 2 peiced it together and freed her, but by this time the horde were ready to invade, together, the 3 collected a large group of Earths heroes (and the Green Scorpion and Metal Batboy, because the GS knew of the "history between his kind and the Horde, so he thought the heroes would "save" him), and with their combined might, defeated the horde.

when the group formed the Justice Gaurdians, Marvinia stayed on, viewing them as a new family.

powers: Marvinia has telekenetic powers, able to read minds and (to limited degrees) even control certain people, she is also a shapeshiftster, able to not only change into her "marvin" form and back, but also look like other people. she can fly and has superhuman speed and strengh. she can make herself intangable or even invincable. her cloths can change shape and become intangable too. she can also retain any form she is indefinite as long as she doesn't deside to change forms (meaning she can stay in her "marvin" form until she chooses to look like something else even if tired or uncouncience). in her true form, Marvinia's tail has a stinger that causes dissyness and uncouncience (sometimes both effects) to whomever stung (including herself)
weaknesses: Marvinia is afraid of fire (a trait coded into all martian DNA oddly enough). she also can't duplicate body traits unpresint if she can't see or study it (I.e.: tatoos covered by a shirt, a scar covered by hair, etc)
trivia:
*Marvinia's species go through a pon-farr type mating ritual every 7 years after the start of puberty.
*Marvinia chose to use her "marvin" form both as a homage to the cartoons she was forced to watch, and to be better accepted by the humans
