Atama nodded, walking off to a distance from anyone around him.
"This technique, I have come to call it, Chaos Unification. Named for how it violently fuses two people together." He said. Atama then started to output an incredible amount of darkness around him, the energy so thick it was impossible to see him with normal eyes.
"The first step is to build up an incredible amount of inherently destructive energy around you. The more energy and the more destructive it is, the better." Atama said. The man then teleported to right where he was standing, the energy adsorbed back into himself, completely normal.
"The second step for the two people using the technique to teleport to the exact same spot. This is the most dangerous step. I'll explain why in a minute. But for this step, it's generally best to be at your highest transformation. Then you are done. If you did it right, you will have successfully fused." Atama said before changing his tone to that of warning.
"But, there are several dangers involved in the technique. The first is the time and the preparation. It requires two people capable of doing this flawlessly, otherwise the power gained might not be enough to defeat an opponent. The two users' bodies are broken up thanks to the energy and teleportation if they did it right, possibly leading to losing a limb if you fail teleport and leave a part of you behind. Secondly, the energy itself is a double edged sword. It has to be destructive enough to break up the bodies of the users, thus potentially destroying them, meaning an energy has to be used in an amount that won't kill the both of them. However, it only grants the bodies strengthened by the energy used, meaning using to little would lead to only a modest power increase. Thirdly, the two users have to be in perfect sync mentally. Because of the fact the two users' minds are deposited inside the new body, so much a single thought could cause a mistake in battle, which could cause death. This is why I have never used the technique more then once in a previous life, or ever taught it to someone. Now, it is possible that someone could alter the technique to remove some of these dangers, or your methods of teleportation and energy don't involve breaking up the bodies of the user. Any questions?"
