Lisa Loud is a character from another Nicktoon, the Loud House. In the show, she is one of Lincoln Loud's 10 sisters, one of the five sisters younger than Lincoln and the second youngest behind Lily. Lisa is the brain of the family, always doing scientific experiments or other things having to do with science, which managed to win her a Junior Nobel Price. In the crossover episode, "The Fairly OddParents Meets The Loud House", she built a portal to travel between Dimmsdale and Royal Woods, which nearly ended up destroying her room and the whole Loud residence.
