Shortly after the fight against Raditz, you will be able to take control of Piccolo and explore the world of Dragon Ball Z Kakarot. As you wander around, you'll come across Tenshinhan and Chaozu - these two characters have a mission for you.
Telekinesis training
For this fight, start by attacking Chaozu: he's not very resistant, but could come and tickle you when you attack his companion. In a few seconds, Chaozu will be out. As for Tenshinhan, keep an eye on his aura: when he glows red, do as usual, move away a bit and get ready to dodge with the right timing.
This fight is relatively simple and if you have thought about equipping the makkenkosapo special attack, you should quickly defeat them. As usual, this fight will bring you a soul emblem with the effigy of its owner.
