I decided to give Kendei the personality of Gohan (during the Cell Saga) and Naruto joined together. That's the reason I wanted him to be in a situation kinda like this:

'The hero has just seen one of his/her friends get killed as the villain claims he/she will proceed to murder the others as well, one at a time. As there is nothing the hero can do about it. The villain gives him/her a choice of "letting his/her other friends get killed" or "proceed to fight mono y mono with the villain, risking his/her own life in the procces".

Kendei starts off every battle in this pose; whether it's just sparring with one of his comrades, or facing death in the eyes. Also, I put sort of an aura around his body to show his power increasing. Although I'm not sure if it is noticable, hehe. Enjoy!
