Expanding Needle Sphere

 is a special mechanical tool designed and utilized by Ryūken Senju to contain super-humans. After the button is pressed on the tool, it forms an airtight sphere around a target to trap them. It is made from compounded super strong concrete laced with 16 layers of Vibranium and 5 layers of Carbonadium. The vibranium absorbs every form of kinetic energy rendering all forms of physical attacks, even the ones enhanced by chakra and special tools useless. It can easily contain chain explosion of dynamite due to the vibranium in it. And, the carbonadium ensures that the contained target does not escape using mind-body switch. Also, if the target is injured the carbonadium drastically slows down his/her healing. Because it is an airtight sphere, the oxygen inside is limited; if the person inside doesn't escape quickly, they will suffocate and die.
