Toeiland kid buu is not stronger than all other buus. buutenks played with ssj3 goku and goku looked actualy scared. buuhan>buutenks. goku never said confidently that he and vegeta could beat normal super buu while he was confident ultimate gohan could do it even with piccolo , goten and trunks absorbed. fact is Toei still followed Toriyamas powerscaling but what a surprise , they failed at making sense of their filler.
