I am gonna try to make some brief (not too large of a bio, but not too small) bios for characters that never had much of a storyline. This would be their MKA storyline as well. I'm gonna do one at a time. Here goes nothin' (seriously):

Name: Chameleon
Origin: Zaterra
Allignment: Evil
Allies: Shao Kahn
Foes: Khameleon, Reptile

Chameleon: My master, Shao Kahn, was thought to be dead, killed by the Deadly Alliance. It was really his clone. Noone knew, except for me. I was the greatest weapon he had. In the battle between his army and the Edenian/Shokan army, I slaughtered hundreds, maybe even thousands of Kitana & Goro's soldiers. Now Kahn is nowhere to be found. One of Kahn's goals was to destroy my homerealm, Zaterra. He achieved this goal, and used me as a spy. He wanted to expand his empire. He had me destroy Zaterra and all of my fellow Saurian brothers and sisters that I could find. Only two escaped. One was Reptile. The other was my sister, Khameleon, I foolishly felt for her and let her go. Reptile became loyal to Shao Kahn, without knowing of what Kahn did to his realm. Khameleon is now hunting for Reptile to try to repopulate Zaterra, and reform it, maybe even break it away from Outworld, but definitely to change Reptile's allegiance.

I cannot allow this to happen. I must find Reptile and Khameleon and destroy them. Long Live Lord Kahn!

Chameleon's Ending: The battle of Armageddon was over. There were five warriors left standing. It was me, Shao Kahn, and three Shokan Generals; Sheeva, Kintaro, and Goro. After seeing all of this death and destruction, and after realizing that I dealt a lot of it, I realized that all of this may never of happened if it wasn't for Shao Kahn. I remember breaking each skull with my bare hand, and severing multiple limbs, and disembowling many brave warriors who were fighting for their home and for what they believed what was right. I then saw my sister, Khameleon, laying in the battlefield, a crow pecking her eye, dead. It was then I remembered when I was blinded by rage, power, hate, agression, and anger, that I killed her. She was trying to stop me. Trying to talk me out of it. I wouldn't listen. It was then I also decided to at least try and right my wrongs. I mercilessly attacked Shao Kahn. He was blindsided by my fury and was near death in seconds. His three Shokan warriors didn't do anything at first due to pure shock. Then when they came to their senses, they attacked me from behind. Kahn was down and I was about to deliver the finishing blow, but I was stopped. I held my own against these four-armed kombatants for a long time. I eventually decapitated Sheeva and kept her head for a weapon, using it sort of as a mace, seeing as the spinal cord hanging from her severed head would suffice for a handle. Of course, it didn't last long against Goro's blades. I momentarily froze Goro with my iceball and then drew out my Axe and cut Kintaro into ribbons. Goro broke free from his ice prison, as I expected, and mercilessly attacked. I hit him with my disabler ball and called forth lightning to strike him, which ended up being all I needed, because it dropped him to his knees. I swung with all my might with my Axe and I watched his head fly off into the distance. I then turned to face my former master, Shao Kahn. But, he was nowhere to be seen. Then, from behind, he struck me in the back of the neck with his Wrath Hammer, dropping me to my knees. Then, while telling me I am a fool and will perish, threw me into the air and hurled his harpoon, piercing me in the heart. It was over. I was so close to making things right.

I tried to make the end be like the cop in Twisted Metal Black's ending, where he's doing it in first person, so you'll think he'll be okay, but then you find out he dies, and could perhaps be talking after death in some kind of hell. But, if too many people vote against an ending like this, I can change the ending.
I did the bio & ending about a year ago. I also did bios for Hornbuckle, MKMSZ's Earth God, & Tremor when I did this one. If anyone would like to see those, just ask.
