Appearance:
In his normal form he has Martian green skin and looks human in form aside from two spikes coming out from each of his shoulders and pure red eyes but in his battle form he is very different. Battle form Man Hunter has very pale, white skin like a white Martian and natural bone like armour that is split up into sections and covers his entire body. In battle form Man hunter resembles a full fledged white Martian but with the exceptions of the white plated armour all over his body.

Apparel/Costume: 
His costume is basically just Martian Manhunters minus the cape and instead of a speedo he has shorts down to below the knees and when fighting crime he tends to try and do it in his battle form.

Powers and Abilities: 
Thanks to his Martian genetics he is able to make limited shape shifting which takes about ten minutes to shift to and from each form. In each form he has access to different powers from his Martian lineage.

Everyday form powers:

-Martian vision
-telepathic
-increased speed
-can become transparent but not completely invisible
-flight
-low grade regeneration 

Battle ready form:

-Martian vision
-increased strength
-increased endurance
-able to stretch to double his size
-can become intangible

Man hunter lacks the Martian vulnerability to fire but still has the abnormal fear of it. That being said he can still be hurt by fire and anything a human could get hurt by while Man hunter is in his normal form but while in his battle form Man hunter has a great deal of resistance against most forms of damage.

Skills: 
He is fairly skilled in hand to hand combat and in his battle form using both his intangibility and elasticity as a way to pull of moves that he would normally not be capable of doing. Man hunter also possesses a aptitude for understanding complicated sciences such as being able to have a basic grasp of say rocket science if it is being spoken to him. 

Personality:
Gray is very social in fact if you were to look up the word social in a dictionary it would probably give you the meaning of the word social but then Gray would come along with a photo of himself and quickly glue it into the book. Gray likes making jokes but often times they're only funny to him but he's pretty ok with that so long as no one points it out. Grey enjoys fighting crime and he will usually do it to take his mind off of things that are troubling him or ,if he's in a really bad mood, he'll just go into his room and listen to the radio. He likes very specific old rock and roll songs so most of the time he can't find a good radio station to listen to so he'll actually get angrier rather than getting more soothed by the music. Gray gets angry fairly easily but he when he does get angry he doesn't get absurdly angry more like very irritated and will bottle up his emotions.
History: Gray started out life as GeneticRebuild-Alpha or G.R-A. He was the creation of a few paranoid genetic engineers who feared the Martians of Mars and decided that they needed a Martian of their own to defend them in the case of an attack. Now, at the time the scientists didn't know most Martians had been wiped out but that bit of knowledge wasn't needed to try and rebuild the original Martian from before the green and white Martians were split into two species. They managed to get samples of green Martian DNA via Martian Manhunter and white Martian DNA via Miss Martian both bits of DNA were obtained during battles that occurred at separate times. 

Now that they had the DNA the scientists had to now figure out the ins and outs of the alien genetic structure. This proved to difficult for the scientists so they decided to bridge the gap between the two DNAs via human DNA which they had more experience in. After finally being able to start the process of growing the alien via test tubes they decided to grow four, each with different genetic structures just in case one Alien didn't survive and that way they would have a higher chance of success. The aliens were codenamed GeneticRebuild-Alpha,Beta,Gamma and Delta. 

After a few decades of them growing the scientists decided it was time to let the now physically teenagers, mentally infant, alien kids out of their growing tubes. Each one came out a bit different and Delta perished as soon as the tube was opened due to something wrong with its respiratory system. Deltas brothers Alpha,Gamma and sister Beta were to now begin basic knowledge transference via telepathic upload in order to give them all knowledge needed to know right from wrong and to see if they could become heroes. 

Sadly that never happend. 

Beta went berserk, killed her brother Gamma, destroyed the facility, made the scientists flee in terror and finally flew away. G.R-Alpha soon found his way out of the destroyed facility and managed to make his way to jump city with out seeing another living person. The first person he saw was a low life thug and G.R-A used his telepathic powers to absorb all his knowledge (the very thing he was supposed to do to the scientists) and basically make himself a almost perfect copy of the man (in mind not body) he then in turn began his life of crime. G.R-A now known as Gray began going on a crime spree robbing, assaulting and destroying property all over the city only to be stopped by the disbanding Teen titans. While being detained Gray remembered when he first awoke and how everything went down hill and now he was detained and probably being sent to a jail of some sort or maybe even killed, but then he remembered the ones who stopped him. A team of those who wanted to do the right thing for the betterment of the world which seemed like a very noble cause. He vowed that if he got out he would use his powers to help the Teen Titans and the rest of the world for that matter while trying to make it a better place. Then as if by fate something inside him snapped and for the first time he transformed into his battle form, used his abilities to phase through the walls of where he was being held and escape custody and possible death. Now even though the original Teen Titans are disbanded he helps out with the new Teen Titans using his new alias Man Hunter in honour of Martian Manhunter.
