|Voiced by|| Megan Dwyer (Seasons 1, 2 and 4)|
Misti Dawn (Season 3)
Nina is a girl who lives in the same house with Dex and Aleks (formerly Lyle). She was originally voiced by Meg Dwyer, a friend of the creators, although her character was also voiced by both Misti Dawn (Season 3) and most recently, Haley Mancini (Bad Alien).
Nina was the first attempt at adding fanservice to the show, which ended successfully and eventually led to the creation of Amanda. Common traits she possesses are her acts of lesbianism, innocence, constant threesomes with the other characters, and most prominently her giant breasts, which results in her becoming a favorite among fans. A running gag in the show is when her boobs bump or get bumped into various objects or people, though her aforementioned ignorance makes her constantly oblivious to how much they constantly get in the way, excluding recently in Bad Alien; her sentiments towards her chest seem to blend between amusement and frustration, though mostly the latter.
Nina is also sarcastic and demeaning, a trait which has grown more and more prominent as time went on, especially after Lyle's passing and Aleks moving in with her. Her overall intelligence seems to vary from episode to episode, but as a whole she seems more selectively naive than stupid. Likewise, whether or not she accepts people ogling her also tends to vary; sometimes she resents being treated as a sex object while other times she seems completely clueless that people constantly stare at her chest.
- Nina was the first animated girl to be shown in the series. She premired in Girl On Xbox Live.
- In the sanity not included comic 7, Nina reveals that she gets her enormous breasts from her father, who has breasts about twice as big as Nina's.
- Nina and Lyle had a complicated relationship.
- It is assumed that she liked Lyle. In Complicated Complications, she is shown to be jealous when Amanda says she has a "relationship" with Lyle.
