what are you even talking about
River is both extremely capable AND extremely goofy. His entire family is shown to be fighters who love to love. Globgor is an eloquent intelligent superbeast.
Marco is dainty but can kick more ass than all of the best mewman soldiers put together.
Heckapoo is irresponsible but ultra-powerful and her chaotic nature is pretty often good-hearted.
Moon lived a hard life and connived against her own daughter to destroy the peace they were building towards.
Eclipsa is selfish and her selfishness is something she's willing to destroy a kingdom over.
Whatever weird GirlPower! stereotypes you're trying to accuse the show of having fall apart if you even bother to watch the show.
Star vs. the Forces of Evil is like the only show that really genuinely is fair to its characters. Tom is like a big weenie but he's also an extremely powerful demon prince and they're just as ready to see him get jobbed as they are to see him kick ass. Star is the ultimate magic user and it took half a decade of extreme personal growth to get there. Very few of the real characters on this show were shown to be one dimensional analogs.
