A relentless foe guns for the Man of Steel on a new “Superman & Lois” (Tuesday at 9 p.m. on CW).

Warning! Minor spoilers follow!

In “Heritage,” Clark (Tyler Hoechlin) and Lois (Elizabeth Tulloch) are still trying to cope with the reality that son Jordan (Alexander Garfin) has inherited at least some of Clark’s Kryptonian powers.

Clark decides to fly his son up to the Fortress of Solitude to run some tests – and to chat with the one person in his life who can make sense of all this.

Lois clashes with Morgan Edge and makes a major life change.

The Kent family attends a barbecue at Lana’s (Emmanuelle Chriqui) place, where her husband Kyle (Erik Valdez) continues to act like the biggest jerk in Smallville and Metropolis combined.

As for that mysterious stranger – now identified as Captain Luthor (Wole Parks) – much more of his motivation stands revealed in this episode.

Is he evil, mad, or something else entirely?

He has his reasons for trying to take down Superman, and he tries to connect with a member of the Kent family to succeed.

One of the smart things about “Superman & Lois” is how the premise is so different from comics canon. Here, Supes and Lois have twin sons, and the story can go in many directions.

Will moody Jordan become Superman’s greatest nightmare? Or will he prove to be a worthy successor to his father?

Will Jordan and non-powered Jonathan (Jordan Elsass) become close or will they become a modern-age Cain and Abel?

In trying to help Jordan, Clark seems to be ignoring Jonathan, the teenager who is at last being eclipsed by his twin. Could Jonathan become the House of El’s greatest foe?

Not even diehard comics geeks can predict where “Superman & Lois” will go, and that makes the show that much more rewarding.
