And continued to be so. Piccolo Jr never stopped being the reincarnation. Toriyama nor Toei went back on the concept. They continued to remind you that Piccolo Jr and Kami were once the same Namekian.
Because that’s how Toriyama wrote it? He clearly had Piccolo rebirth himself and be spared by Goku so he could do a redemption story.
why?. if it is supposed to be the same
Because that was a gradual change. He only teamed up with Goku to stop Raditz. He only sacrificed himself to save Gohan after bonding with him over a year after kidnapping him to use him as a tool to fight the Saiyans.the piccolo that did not care if the people died in 23 tenkaichi does not seem to me exactly the same one that managed to save gohan from dying and even ignoring this ...
Nobody is saying Piccolo Jr is EXACTLY like Piccolo Daimao. The argument is if Piccolo Jr and Piccolo Daimao is the same person. They are. That’s why Piccolo Jr and Kami are considered the same person.
Think of if this way Boo and Oob are the exact same being. Oob is the reincarnation of Boo. They have a completely different personality but they are the same being.
The method of reincarnation is different but the concept of being reborn with a different personality is the same. Piccolo it Jr was still evil he was just less evil and it was a gradual shift .
He at the very least clearly planned on it by the time he was writing the 23rd Budokai when Shen/Kami and Piccolo Junior are having an alien conversation.annyway I'm sure the author was not planning that they on being aliens when they were originally demons
And it’s been said before that Piccolo is both a demon and an alien. They’re not mutually exclusive. He’s an alien because the original Namekian is from Namek. He’s a demon because he was created from the evil within that was expelled from Kami.
Majin Boo, Piccolo Daimao, and Garlic Jr are all considered demons and they’re also aliens.
