Will is taller and more muscular, but he is still slim. He wears overall the same clothes as before, with a single shortsword in a sheath tied to his belt.
Will is a kind-hearted individual. He puts the safety of others above his own and is quick to defend anyone. Many people have stated that he is not the one to kill. Zirconium R. Erik has stated that he (Will) is "too kind" sometimes.
