Goku and Vegeta swaps abilities and powers, just in case they might be tracked down by a unknown supervillain and a bright white-silver is drawn and spiking all over Vegeta's body and his hair, eyes and eyebrows are silver & white, also Goku has the Ultra Ego of the gods and the slightly evil personality of the gods too and Goku sports purple hair, purple eyes and purple eyebrows and he has a smug grin on his face. Ultra Ego Goku: slightly evil smirk. "I'm going to enjoy the destruction power of the gods!" >:D He said in a dark, evilish voice of a super villain. Mastered Ultra Instinct Vegeta: smirk. "I actually feel the power of the angels, flowing right through my veins and it's actually amazing, Kakarot!" ;)
