When Sora first saw the creatures of darkness, he was afraid but the power of light gave him the Keyblade so that he can fight off the darkness. Later on, Sora meets his two faithful companions which are Donald and Goofy and they helped him fight the creatures of darkness. Eventually, these three become friends and travel around various lands to get rid of the darkness surrounding it. Later on, they find Riku, one of Sora's friends, and he took Sora's keyblade as he claims to be the "Keyblade" master and was shocked that he too was a keyblade wielder. Then Goofy and Donald leave Sora for over Riku and just left him. Sora knows for a fact that he is the true keyblade master so he can't give up on himself.
Epic heroes all have different personalities to one another but they are similar one way or another. When I was young, I didn't really have any friends and mostly did my homework and played video games myself. I was very shy and didn't socialize a lot around people which made it harder to find any friends. Eventually, I realized that the heroes in video games sometimes had companions with them and they were friends with one another. They were very calm about what they say and had solutions if they had any situations or problems. I really wanted some friends just like them so I started to talk more socially around people and made some friends. The epic heroes that I looked up to helped me to socialize more around people to find some potential friends and also helped me to not be shy anymore and be brave.
