Avion was deep in thoughts from what Naron said earlier. It heavily hit him.
If he did not use his powers, he would immediately feel tired much earlier than Temon who is considered the weakest of the three.
Avion was extremely weak. This is because as long as he would become tired, he would revert his state.
Before he came to that world, Avion could control the universe's time without any effort. His daily life was easy due to his power and there was nothing that could make him tired.
He was weak both physically and mentally.
When Avion heard Naron's words, it inspired him and made him realize what he was lacking the most. That was strength. Not just physically, but even mentally.
Avion was impulsive and would act on thought. That was because he couldn't bear to become uncomfortable for all his life everything went his way. It suddenly became clear to him - How his deaths taught him a lesson.
