Agent Lasa is young, blonde, and exceedingly angry. She is prone to tension headaches and other symptoms of too much stress brought on by poor punctuation or vocabulary choices. She works in the Department of Angst with Agent Montbretia. Lasa's favourite method of dealing with her headaches and stress, without resorting to drugs, is to beat herself around the head with a book until wooziness sets in. Montbretia does her best to prevent this. Lasa and Mombi helped out in the assassination of 'Land Before Time: Littlefoot x Cera'.
