Margo, an innocent girl who is witted and pretty much cute in every possible angle, but then Gru starts to see what has happened to her little angel, but instead of stopping it, he used it in something more, fun.
Gru has been married to Lucy for about a year now, and it seems that all of Margo's sisters are technically grown up, yet doesn't know what is the real meaning of love and those, as they say, icky and just stuff. But then they seem to realize what it really means and how it works.
