Habe ich gefunden und gelesen. Da sind aber keine Belege dabei.
Das englische Wiki, das logischerweise immer besser und ausführlicher ist, sagt sowas nicht.:
Fusion: Nameks have an assimilation technique where they are able to permanently join themselves with other members of their race. When this is done one of the Namekians serve as the base and gains the skills, memories and many of the personality traits of the other. It is unknown what happens to the soul of the fused Namek, but it is hinted that the other soul simply remain with the body until it perishes, or that, at least, the personality and memories are, to some extent, present within the host being. This is evident when Nail talked to Dende through Piccolo, proving that Nail's knowledge and personality were still present (although this was only in the anime), to an extent, or when, after the fusion of Kami and Piccolo, Piccolo's personality changed somewhat. The Namek fusion will not obtain any caste specific abilities from the other. This is shown when Piccolo, a fighter-type, is unable to restore the Dragon Balls, even though he had fused with Kami, who was a member of the Dragon Clan.
Das deutsche Wiki ist voller Grammatik und Rechtschreibfehler, und in einer eher umgangssprachlichen, unsachlichen Sprache. Und wie gesagt, ohne jede Nachweise.
Du bist da ziemlich sicher falschen Infos auf den Leim gegangen.
