>>124069846ben 10's merch sales were very good for the first two shows. Then bandai got super fucking greedy and wanted to make all these bullshit playsets with one exclusive figure, exclusive figures to other countries and then bullshit like the color swapped aliens where it was just echo echo but with goop's paint job.
then the stuff stayed on the shelves because no one needed 5 different diamondhead figures, plus with omniverse they randomly shoved entire seasons into a 6am timeslot
yet newer shows seem to be doing fine without any merch, like steven universe or even TTG
