I put the Z-Fighters of M8 considerably higher than Vegeta and Trunks when they fought Cell but much lower than their Cell Games counterparts. I have Cell being 10% stronger than Goku in their fight but over I have Goku being 40% of Cell at his max. I have Broly being 50% of Cell overall.
Cell Games
Full Power Perfect Cell: 250
CG Gohan: 125
Cell (vs. Goku & Gohan): 112
CG Goku: 100
CG Vegeta: 70
CG Trunks: 69
CG Piccolo
That is better evidence than what Pakl has ever given lol.
My counter - why is Piccolo considered to be anything if he has not also gone into the RoSaT? Piccolo went in after Goku and Gohan, so it makes no snese for him to go in if Cell was already defeated. It makes it seem like Goku/Gohan went through the whole RoSaT process, but Toei nerfed the shit out of Gohan.
Cell has been defeated. Goku is not a ROSAT waster. Piccolo feeling left out, decides to give himself a go in the ROSAT because of how surpassed he is. Mr. Popo gets him out the ROSAT when everyone leaves to chase the Legendary Super Saiyan.
To be honest, I don't think that Piccolo would be a RoSaT waster either in this potential scenario. After all, he basically gave up trying to catch up to the Super Saiyans after the Cell Games, despite still having 24 hours in the RoSaT.
