It’s a battle of the old and the new. Yusuke and Gon are the main characters of 2 manga that were written by the same person. However that doesn’t mean that Gon has a chance against Yusuke. Yusuke has more experience and has more thug experience. Plus Yusuke has his super spirit gun and demon form. He also has a giant aura. Gon has an aura but it’s not nearly as strong. Yusuke wins.
