I wouldn’t call that “significant damage” since Piccolo isn’t weakened at all and Goku even saya it. A full power Kamehameha was almost always a special finisher so definitely a good amount above the user.
Not sure.
He was useful against Nappa and Vegeta, and only dismissed from the Raditz fight because Goku was afraid he’d die again. He and Gohan saved Vegeta’s life vs Recoome and never stopped helping against stronger forms of Freeza.
He’s strong enough to “help”, but we don’t know what kind...
Gohan said they only might stand a chance vs 1st form. Vegeta definitely overplayed his hand here, or maybe he was hoping to become a SSJ in the fight. Kuririn and Gohan’s powers were growing too.
Goku was definitely worse than Vegeta after the beam struggle. He was in no condition to fight anymore. After the Ki ball, I like to think Vegeta put himself at a big disvantage. He’s not weaker tha Goku, but KKx2 Goku would’ve kicked his ass.
He said it on twitter because fans keep pestering him about power scaling questions back a couple years ago.
Agreed with all your arguments, but I think the comparison makes sense (they have similar narrative purposes) and nothing contradicts it. Hatchy even got forms similar to Cell (Giant and...
Scouters weren’t common thing back then, so Cold’s power would be completely unknown to most.
Long ago Cold was the central figure, but when Freeza got old enough (which is before Vegeta was even born) he took a step back.
Did Vegeta know Cold when he and Freeza went to Earth?
