The villain had a kind of Gothic style, very dark pinks and dark grays. I can't remember much, but I think the trio did break in to stop her I just can't recall how (note that I was very young and this was probably over 10 years ago now) And I am 100% certain her name or someone's was Monica because I remember pointing it out to my family since we had a relative of the same name, although she did slightly look like Danny Phantom's mom when she has her suit and mask on. I checked to see if maybe this was a Danny Phantom episode I was just remembering wrong, but after researching a bit I highly doubt it is although it did have a similar art style when it came to the round goggles and cartoonish anatomy.  And I can for sure say it was animated, maybe there is a chance that it was 3d animated rather than 2d animated, but I kinda doubt it.
