Well, it depends on the specific story. Maybe it's mentioned clearly in the first few pages or paragraphs. You might need to look closely to get the exact age.
Well, without more context, Ralph could be anyone. He might be the author's alter ego, or perhaps a fictional character from a particular genre like a children's storyteller or an old man sharing his life experiences in a fictional town. In any case, we need more details to really know who Ralph is.
In the fanfic, Johnny's character might be more developed. In the original, his story was somewhat limited, but the fanfic could expand on his backstory, his thoughts, and his emotions more comprehensively.
Ralph and Shank's relationship could develop in a really interesting way. Imagine if they had to team up to compete in a special tournament that spans multiple game worlds. As they train together, they would learn about each other's strengths and weaknesses. Ralph would see Shank's strategic mind at work, and Shank would come to appreciate Ralph's never - give - up attitude. This could lead to a deep respect and eventually a strong friendship or more. They might also introduce each other to their friends in their respective games, which could bring about some really fun and chaotic interactions.
