Do you mean George Harris? George Harris is quite a different slave than Uncle Tom, for example. He is neither a martyr nor is he even pious. He is discouraged at the lot life has handed him, especially because he cannot live up to his enormous potential and keep his wife and child safe. Thus, the character of George is effective because it both puts a more human face on Stowe's representation of slaves, in contrast to the angelic Tom and Eliza, and George is also an example of a slave with his own agency who is willing to fight to keep it.
