Answer:
there are many different ways this can go.
in my opinion id say a lot of shows now a days have similar plots and story lines but just different characters, names, and settings.
if i had to choose two characters that shared similar experiences id say they would have to be twilight sparkle and naruto uzamaki.
both shows are completely different styles and ways of portraying the message at hand but both shows are about learning from your mistakes and making new friends.
naruto has a new mission each episode giving him chances to meet new people and make new friends. each episode he goes on a mission and almost always meets someone new. he has a gift for making friends and helping others. same goes in my little pony with twilight sparkle or the other ponies in mane 6. each character goes on a friendship quest to solve an issue between friends and learn a lesson in the end.
both shows portray important life lessons about friendship and morals.
