Lucille Bluth, or "gangy" to her grandchildren, is the matriarch of the Bluth family and easily the most ridiculous of all the characters on Arrested Development, and trust us, that's impressive. Lucille is the mother of Gob, Michael and Buster as well as the adopted mother of Lindsay and "Annyong."
Lucille loves living a lavish lifestyle complete with extravagant condo, trips to the country club, and housekeepers to boss around. Lucille is also a frequent alcoholic and loves destroying her childrens and grandchildrens' self esteeem, especially Lindsay and Maeby.
During the season finale, it's revealed that Lucille was actually behind the illegal activities of the Bluth Company.
Lucille: If you're saying I play favorites, you're wrong. I love all my children equally.
(Earlier that day)
Lucille: I don't care for Gob.
Lucille: (showing Michael her fox scarf) Michael, look. Look what happened to my fox. Someone cut off its little foot. Is it, is it noticeable?
Michael: Well, you've got to remember you're going to be all splattered in red paint. That's gonna distract the eye.
