Let's see how you all react to this eh?
Mel-rahk was originally one of makuta's experiment's, he is an EV-rahk, an intelligent rahkshi who would be harder to defeat. The only problem was that makuta had made him too smart, after he first saw the toa he decided to fight on their side once he saw what they fought for. Makuta captured him when he tried to escape, he sliced part of Mel-rahk's mask with his claws then threw him into the volcano and left him for dead, what he didn't know was that Mel-rahk had managed to grab onto a small outcropping and pulled him self back up but not before the heat from the lava had melted his suit. After that he gained the toa's trust after he managed to save a village that he knew makita was going to attack.
Attitude: generally seems blank but can be very friendly, happy (rarely) and angers quickly when a friend or himself is hurt.
Attributes: hates makuta, has a mild Fear of lava/volcano's but can generally fight it, will do anything to protect a friend, if he's bretayed he will hunt down the betrayer and kill him/her no matter what.
Weapons: two staffs, right shoots out flames or can heat up enough to cut through pretty much anything, left sends out sonic booms/waves and if jabbed into the ground can cause mini earthquake's.
