I'm not so sure Vegeta would kill everyone. If anything he'd probably force Dr. Brief to build him a spaceship and/or the gravity chamber, since having Goku attain the SSJ first obviously hurt his pride and he'd want to surpass Kakarrotto even if Goku is dead. Since he hadn't succeeded by the...
I think he was made sociopathic due to his life circumstances. The series doesn't seem to imply he was born remorseless, hence the whole explanation that Nina was the one who experienced the cruel events at that hellhole but Johan was the one who internalized those memories as his own and became...
Minimally. #16 made it sound like Vegeta was still comfortably ahead which was why he was confused when Vegeta got frustrated with Cell and Cell was completely composed.
The island's worth of people that Gero and 19 killed also weren't revived, since the wish at the end of the Cell saga only specified those killed by Cell.
All it takes is one trip to New Namek to revive them lol, shitty as hell excuse.
But yeah AT probs does like the OG DB characters more. Same reason why he'd rather resurrect Freeza again and again instead of giving other villain characters more shine.
SPC's Kamehameha has to be way above Semi's explosion and it took that level of power (and more) to kill Cell. I don't think SSJ2 Gohan would face fatal injuries just from Semi's explosion, other than suffocating due to the lack of a planet to be on.
Semi's explosion being able to kill SSJ2 Gohan can be said to just be a byproduct of the planet exploding. The most it's been shown to be able to do is kill SSJ Goku.
The new Broly movie gets overhyped by fans, I'll give you that. But M8 tried so hard to be different than previous half-hour flicks only to devolve into a roided up idiot using Kakarot and cheesy one liners for 25 minutes only to be defeated by the power of friendship. How Toei thought Broly...
