Stereotype in Comics, Animation and Gaming Narrative

What is your opinion about the use of stereotype in comics, animation and gaming narrative? Is stereotyping ultimately a necessary strategy in character design and representation?  Do you think you have personally been affected by stereotypical representations?

Personally, I don't mind the use of stereotype in comics if that's the best way to tell the story. Furthermore, in comic books, the publishers tend to use over the top ideas and concepts to sell their comics, this usually comes in conflict with the comics' actual stories. As for the character, I think people always have some different personality in real life, but not that obvious like in comics or animation.  However, to make the character stand out, they have to exaggerate some part of the personality of the character, I guess that a small reason causes the stereotype. Therefore, I think it's still a strategy in character design and representation. I have been affected by stereotypical representations, like when I read a hero character achieves God-like powers, usually after some disaster or twist of fate happens to him/her in their personal life, and then I will think the character might go mad and go on a rampage on the planet; leaving the hero's friends having a hard time by choosing either saving their friend from him/herself or just kill him/her.
