This is a tribute to Dragon Ball: SuperHero. The rivalry and comparisons between Piccolo and Pikkon have always been pretty solid. Pikkon was able to hold his own against Goku at near SSJ2 levels for a while there so the guy is extremely tough and you could make a decent case for him holding his own or maybe having the advantage against Piccolo for a while there. Nowadays the comparisons are fairly one sided as Piccolo will always be the strongest Namekian going forward but he needed to symbolically confirm this with a victory here. Piccolo wins.
