Help naming the twins plz? o3o

I'm having alot of trouble naming them, thier opposite twins. They were trouble since they were little, mainly bullying the littler kids, but then as they grew older, they got worse, robbing banks and jacking cars are just a few examples. The male of the two has a major weakness. He talks big to bigger people, but never hurting girls. While the female of the two is the worse of the two. The only thing the female is scared of is pink. And thier spieces is some sort of rodent. Sorry bout the long backround info.
