Akko is my dear daughter!
Was both of the DKL games really notable titles as DKC? I'm not sure it's one of the known roles K. Rool was known for.Namely he served as the primary antagonist for 5 Donkey Kong games. (DKC 1-3, Donkey Kong Land 1 because 2 and 3 were just ports of DKC 2 and 3, and DK 64) and lead the Kremling forces.
Imagine if Bowser disappeared from Mario after Super Mario 64 except for some very small games most people forgot about and another character's spin-off sports game, and there were only 3 other "big" Mario games that were 2D platformers released afterwards without sign of Bowser, Goombas, Koopas, etc, and the boss of said third game did a lot of attacks similar to Bowser. Bowser would still be very important, arguably "Needed" to the vast majority of Mario, but just not recently.
Still that's not enough to cover it for me that he's really the "iconic" antagonist he is.
