Cómics, Mangas, Comunidad!

It's cool that Kami is helping them out and all, but I gotta say that it makes not much sense that he's risking his life when his life is the only thing that allows the DBs to continue existing. If he were to die here, then nobody that was killed by Raditz could be revived especially since nobody knows about Namek and their set of DBs at this point in the story.

Also I would've loved to see a story where Raditz wins, but the DBs revive our heroes, so it's no sweat. It'd also be a great way to explain them getting strong enough to defeat the Saiyans (Vegeta & Nappa) without Goku and then later somehow manage to beat Cooler. Sure one might think that there is no reason for Raditz or Vegeta and Nappa to come back if Raditz wins here, but maybe Cooler could think that it'd be a good idea to conquer this Earth place and maybe recruit any of the remaining strong Earthlings into his Cooler Corps (I'm calling it this cuz Frieza Forces initials are FF, so it'd be cool if the Cooler equivalent was CC [not to be mistaken with Capsule Corporation]).

Actually he shouldn't be seeking to retrieve Kakarot to help Kakarot complete his original mission. Raditz in DBZ and all DBM Universes except U3 came to Earth to get Kakarot to come help the Saiyans (Raditz, Vegeta, & Nappa) clear out another planet (unspecified in DBZ, but DBM showed us that it was Helior in the U13 Specials). I'm assuming it's the same mission in this Universe too except in this Universe Cooler gave the Saiyan Trio the orders to clear out Helior instead of Frieza like in the other Universes. They likely like other Universe's counterparts of them realized that 3 Saiyans isn't enough for the task and Vegeta ordered Raditz to retrieve his brother so Kakarot could join them as a 4th member.

So my point still stands with it not making sense that Kami would come help them out unless he for some reason thinks Raditz is here to eliminate all of humanity. Did Raditz even mention that that was why Kakarot was supposed to be on Earth? If Raditz did mention that tidbit at one point or claimed he'd do what his MIA brother was sent here to do before he left Earth, then I guess it makes sense for Kami to join for the assist, but then again still waiting to let Raditz kill everyone and then revive them with DBs so they can train in the HTC and defeat Raditz before he wipes out humanity would've been a smarter plan for Kami to choose in that case. I actually disagree with your assertion that they aren't strong enough to withstand training in the HTC; Goku wasn't strong enough as a kid in the original when his PL was under 200, but he had no issues training on King Kai's planet under 10x gravity with a mere PL of 400 something after being killed by Piccolo when the SPC killed both Raditz and Goku. Yeah I understand the HTC has a limit of 2 people at a time, but the gains that 2 would get from a year of training under 10x Earth's Gravity and the intense rapidly changing temperatures of the HTC would easily be enough for those 2 to defeat Raditz especially if they brought a supply of Korin's Senzu Beans to speed up recovery time between training sessions to allow more training time. I'm sure that Raditz couldn't wipe out all of humanity in a day with his PL and flight speed capabilities if he thought killing 100 hundred humans in a day was enough for Kakarot to prove himself worthy of joining Raditz in leaving Earth in the original series. Raditz was only like 2.5-3x higher PL than Goku in the original series so maybe he could manage to pull off killing 600 humans in a day if he was putting his heart and mind to the task and that's with me assuming he could kill humans 6x more efficiently than he expected Kakarot to pull off in a day's time due to a 3x higher PL and the whole evil morality instead of Kakarot's good morality.

J'attend chaque pasges avec impatiance ! je m'en fiche si cela n'est pas cannon, c'est bien raconté et moi j'aime ça!
