It's about two boys and one girl, they're all martial artists. When I watched it as kid it always played on Megamax. All I can remember is that the girl had black hair and one of the boys had hair accessories like Japanese culture.
There's one specific episode I remember and it's about how said boy I mentioned earlier tries to be as good as his idol but later finds out his idol is his dad. I do not remember more but it's been stuck in my head for weeks and I can't remember what show it was.
I grew up in Romania and watched it there so I am not aware if the show was only published in that country but I doubt it.
The antagonist lived with a giant glass on his head and his partner was not human (some sort of anthromorphic wolf or big food if I'm not mistaken).
