Billy Boop

Billy Boop is Betty Boop's baby brother. He makes his first appearance as her sibling in Stopping the Show, which he can be seen watching his sister perform on stage from the audience. In earlier cartoons he had no relation to Betty for example in the Fleischer Studios cartoon Russian Lullaby he has a complete different origin story and mother. In Minding the Baby he was called Aloysius and was the baby brother of Bimbo. Billy also appears in the early comic strips. Betty tells her director that she thinks her brother has talent, so he puts him up for a screen test. In the comics, Billy is a tough little boy who speaks using a deep Brooklyn accent. He would alternate appearing in the strip with Bubby Boop, another of Betty's siblings. He made a cameo appearance in a Popeye cartoon and his final appearance was in Betty Boop's Hollywood Mystery.
