Oh my God! Looks what happened:
Beast got fat and the X-Men are smoking!
In what has become a major Marvel trope, bad guys (Blob and Unus) rob a bank disguised as X-Men.
The mastermind behind the plot: Lucifer. He’s picking a fight with the young mutants, apparently in order to force them to listen to his long-winded and bizarre origin story involving an alien computer, and to rub it in that he crippled Charles Xavier.
Lucifer gets the kids in a deathtrap.
But of course they escape. And Jean beats Lucifer with his own cape.
An artist other than Jack Kirby and Steve Ditko gets a plotting credit (congratulations Werner Roth!), and the script is by both Stan and Roy.
It’s not good.
