Given the choice between a movie and a TV show about Superman, fans will almost always choose a standalone film. Yet, time again, a TV series like Superman & Lois offers more opportunities to explore the comics the series is based on and, more importantly, new characters.
While Superman & Lois is already introducing plenty of new and intriguing characters like Jon and Jordan Kent, the nefarious Captain Luthor, and the ever-shifting Captain Lane, there's still room to grow. Although some characters should remain in the realm of comics, others could make a big splash in the acclaimed Arrowverse series.
Introduce: Bibo Bibbowski
Despite Superman & Lois taking place in Smallville rather than in Metropolis after the events of the pilot, there's still the need for Metropolis to have some connection to the series. Maybe in one episode, the Kent family could return to the bustling city and Clark would take his sons to meet Bibo Bibbowski.
A massive fan of Superman, Bibo is a tough yet gentle-hearted man who's been saved by Superman numerous times. With Jordan's developing powers, it's possible Clark would show his son all the good his powers have done and introduce him to Bibo.
Shouldn't: Emil Hamilton
There are a couple of reasons why Emil Hamilton shouldn't join the series. While the scientist does already exist in Supergirl, a series on its last season, as a female version, there's still the chance that Hamilton could pop up in the series, serving as a scientist for General Lane.
However, it doesn't feel necessary to add him. Clark seems to be self-proficient and turning Hamilton to the dark side as a way to make him a foe for Clark wouldn't feel right either, given the CW's habit of turning heroes into villains and vice versa.
Introduce: Pete Ross
All fans know that Superman needs a pal to back him up, a good friend who's always there for him, like Jimmy Olsen. While the Arrowverse does have Jimmy Olsen already running around, there is room for another friend of Superman to appear, Pete Ross.
Clark Kent's childhood friend, Pete Ross, if anything, makes more sense to appear in the series than Jimmy Olsen. Pete could return to Smallville and reconnect with Clark, maybe even learning of his secret identity and becoming his new best pal.
Shouldn't: Steve Lombard
While Jimmy Olsen has always been Superman's pal and buddy in and out of the Daily Planet, there are those who don't like Clark Kent or even Superman. Someone like Steve Lombard, a full of himself reporter at the Daily Planet who constantly butts head with Clark.
Although given a brief reference in the pilot, Lombard, although a staple of the comics, wouldn't add much to the series. Even if he showed up in a brief cameo, it doesn't feel like Lombard would contribute much to the series besides his pig-headedness.
Introduce: Steel
The fun thing with adaptations is that not everything has to be exactly like the comics. Things can change and heroes can be different. With Superman out of Metropolis, there's the possibility that the city will need a new hero, perhaps someone along the lines of Steel, not to be confused with the Legends Of Tomorrow Nate Haywood, who shares the same name.
A brilliant scientist, John Henry Irons creates a metal suit fashioned after Superman to take on crime after the hero's demise. Steel taking over in Clark's absence would provide an interesting dynamic between the pair and give Steel a proper live-action appearance.
Shouldn't: Booster Gold
Now, as weird as it sounds, Booster Gold has a bit more connection than Superman than meets the eye. Hailing from the far-flung future, Booster Gold is a down on his luck nobody looking to become a well-respected hero in the 21st century.
When Booster arrives in the present, he sets up shop in Metropolis. With Superman now in Smallville, Booster could, like Steel, be a good replacement. Yet, Booster's antics and goofy nature truthfully make him a better contender for Legends Of Tomorrow or even his upcoming web series than Superman & Lois.
Introduce: Krypto
In comics, man's best friend is still a thing. While a version of the goodest boy to grace DC comics is currently in Titans, that's not to say Krypto the Superdog couldn't appear in Superman & Lois.
A dog with Kryptonian abilities, Krypto's always been a staple of Superman comics and has time again proven himself to be a worthy ally to Supes. From being Jon and Jordan's new pet to helping out in the fight against Captain Luthor, Krypto would be a more than welcome addition to the series.
Shouldn't: Streaky
Most DC fans know who Krypto is and even those outside of the comic world recognize the classic canine. Other super pets, however, are a little less than noticeable and Streaky the Supecat is one such superpowered animal.
Sharing the same attributes and powers as Krypto the Superdog, the only real difference between Streaky and Krypto is their species. As such, adding in the lesser-known Streaky over the much-loved Krypto, especially in a series about Superman, would seem like an insult to the show and character of Superman.
Introduce: Power Girl
As down-to-earth as Superman & Lois appears to be, there are some otherworldly aspects to the series. With the introduction of an alternate Lex Luthor as Captain Luthor, the possibilities for alternate earth heroes and villains have been made more possible.
With this, perhaps Power-Girl could join the Superman family. Hailing from Earth-2, Power Girl is the older version of Supergirl, having taken on the mantel at a much younger age. It would be an interesting dynamic to introduce to the series, an older version of Supergirl Clark could bond with.
Shouldn't: Superboy-Prime
Out of all the alternate earth's and heroes to choose from, there are, of course, plenty of villains as well. That being said, it may be wiser to steer clear of some villains, like Superboy-Prime, an alternate Superboy who went insane.
Hailing from an alternate earth-like Power Girl, Superboy's planet was destroyed in the Crisis, and after Lex Luthor manipulated him, turned on the world. Truth is, with a dark version of Superman already being introduced via Captain Luthor's world, Prime would be one evil version too many.
