text: In the comics, Alexander is reminiscent of Reggie Mantle. He has a crush on Josie and often tries to divert her attention from her boyfriend, Alan M. He is blunt and critical towards Alan M., regarding him as all brawn and no brains. Occasionally, Alexander will take an interest in Melody, particularly when Josie is unavailable.  The interest seems genuine, since, unlike other boys, who fall helplessly in love with Melody at first sight, Alexander tends to remain composed around her.
  Alexander's personality is markedly different in the animated series; he is much friendlier, though no more dependable and far more cowardly than his comic strip alter ego.  In this context, he most often serves as a comedic foil for Alexandra's constant scheming.  The animated version of Alexander also exhibits no romantic feelings towards Josie, tends to gravitate towards Melody or Valerie, depending on interpretation, and is very similar to Shaggy Rogers from Scooby-Doo.
  The animated depiction of Alexander was voiced by Casey Kasem, who also voiced Shaggy. In a 1973 Josie-guested episode of The New Scooby-Doo Movies, Alexander and Shaggy both appear on-screen together for quite some time.  Alexander was played by Paulo Costanzo in the 2001 live-action motion picture. He appears
  as a supporting regular character on The CW's live-action series Katy Keene, portrayed by Lucien Laviscount.
