Mongul is back to settle the score with Superman and he's not alone. He's brought his lovely sister, Mongal, to share in the kill. But the Man of Steel is not without his own backup, and Krypto's bite is far worse than his bark!

Clark Kent and Lois Lane have taken Krypto for a stroll to the park. Then Superman's old enemy Mongul comes down. Krypto attacks at once, with Superman joining in, shortly afterwards. But more surprise awaits Superman.

Mongul has brought with him his sister, Mongal. Together they give Superman a tough fight. But Superman is able to shake off both of them. Mongal escapes, leaving Mongul behind to be taken into custody.

Superman thinks it will be safe to leave Krypto at the Fortress of Solitude and acts likewise.
