If Piccolo (after fusing with Nail) killed off Second Form Freeza before he transformed again and as soon as the Namekian did, he demands Vegeta to take him on so he can finish him off as promised. Looking forward to the challenge, Vegeta prepares himself for the fight.
Could Piccolo (Post-Nail fusion) beat the Saiyan Prince even long after he had gained a few Zenkai Boosts during his visit on Namek?
Or do you see Vegeta coming out on top?
Also, if one or other dies, what would Krillin, Gohan, Dende and Goku (once he's heal from his wounds)'s reactions be soon after the fighters already had their death match?
Note: The scenario and whatever events that'll take place here is in an alternate Namek Saga.
