While he was one of my least favorite heroes in the game, I can’t hate on our Namekian friend.
In the story, Piccolo doesn’t have a huge role. He mainly tags along as Goku and the rest fight Android 21.
But he does play a role in her defeat.
In the story, I didn’t use him much. His moves don’t have much ki based attacks and I found that lacking in the power department.
Same thing against human players online. I didn’t do too well with Piccolo there either.
