The Lonious Monk
Celestial Souljah
This is why the show is trash, only two characters matter when everyone should be leveling up
That doesn't really make any sense given the context of the story. Remember, the DB story starts out on Earth. All the characters are humans and their strength makes sense given human standards. DBZ expands the universe. Humans aren't that powerful in the universe, so why would anyone expect the humans to keep pace? The fact that they continued to have relevance up until the Cell Saga is good enough.
