A selection of my favorite Urusei Yatsura characters.
Lum Invader (pronounced and sometimes romanized as Lamu) is a cute alien girl who once tried to invade earth with her family, after failing she falls in love with Ataru and decide to become his wife against his will. Most of her classmates worship her but she stays always faithful to Ataru.
Despite what it may seem Moroboshi Ataru is in fact the main character of Urusei Yatsura. He is an energetic 16 years old who focus exclusively on "girl hunting". He pretends not to love Lum who disapproves of his hobby, eventhough his true feelings towards her are made obvious on a few occasion.
Mendo Shutaro is the heir of the rich and respectable Mendo family. He is a charismatic, handsome, rich and well-mannered boy. Also Ataru's archenemy aswell as closest friend. All the girls are crazy for him but he is engaged with Shinobu despite being secretely in love with Lum.
Miyake Shinobu was the girlfriend of Ataru before the first episode. She is pretty and gentle but can turn extremely dangerous when angered, which often result in desks being thrown. She has her fair load of admirers including the boss of a juvenile gang, a cute fox and of course Ataru.
Fujinami Ryuunosuke is a character introduced late in the anime. She is a girl raised as a boy by her violent, sea-loving father. She therefore developed a manly attitude and a quick to fight personnality which made all of the freshman girl to fall in love with her, but she longs of nothing more than to be feminine and to finally have enough money to afford a bra.
