This week’s character showcase #21 features Raditz from the Saiyan Arc. He was the one of the last remaining Saiyans in what we would know as Universe 7 and he went to earth to recruit his brother to join Nappa and Vegeta. He had some memorable scenes like when he was shot at immediately upon arriving and also kidnapping Gohan, but his time on earth ultimately didnt last very long. You can read about him on the official site.
Note: His double Ki blast was a real annoyance during the first chapter of Dragon Ball Z: Kakarot but if you were fast at dodging, you could eventually take him down.
