Super Saiyan said:Definitely just the arm. He is shown standing on both legs with no effort, and you can clearly see the blast connecting with his arm/shoulder.
Definitely. It's pretty telling from the fact he was completely lacking lightning when he went on about having less than half his Ki, yet it suddenly appeared after his dad's pep talk. Definitely a case of losing shouki and yuuki.GreatSaiyaman123 said:I think Gohan got that weaker because of lack of confidence, rather than his arm. Not only he easily uses all of his power again when Goku helps him to, but losing limbs has never been known to take away so much power.
