Ensemble Dark Horse / Jeremiah

• Wasteland Warlord Theo is only in eight out of thirty-five episodes and can be the biggest Jerkass in the show at times, but she is still easily one of the most popular characters in the show. Put it down to how she gets some good Rousing Speeches and Jerkass Has a Point moments and has an interesting Back Story and some good Character Development.
• Elizabeth only appears sporadically throughout season one, but is one of the best-liked recurring characters from Thunder Mountain , largely due to her chemistry with Kurdy and being played by Kandyse McClure.
• Ezekiel only appears in six episodes, and rarely for more than a couple of minutes, but he has a strong fanbase for being a Mysterious Protector with some Good Is Not Soft moments and a rich history with Jeremiah's family.
• Gina, a New Meat soldier in The Alliance's army, doesn't appear until six episodes before the end of the show but makes a strong impression due to her quick Character Development and Took a Level in Badass moments, and good platonic chemistry with the main cast.
• Rachel, the leader of La Résistance against Daniel in season 2, only appears in two episodes, but is a fun character to watch when she shows up.
• Dr. Paul Weil, Ezekiel's father, is mentioned in multiple episodes, but only appears in flashbacks in "Rites of Passage", where he makes quite the impression as a deeply depressed Badass Bookworm and The Atoner.
• Phil, the Asian and Nerdy member of Theo's group of inventors from her old school, only appears in the pilot and the two-part season one finale, but is notable for having some Plucky Comic Relief moments while still being a competent engineer and Back-Alley Doctor who remains loyal to Theo through thick and thin.
• Clarence is always interesting during the few episodes in season one where he appears as a hooded Mysterious Informant, and his popularity only increases after his final appearance, where he takes off his hood to reveal that David McCallum plays him and explains that he survived the Big Death as an adult by being The Immune.
• Thunder Mountain scout Simon dies in the pilot (although he is mentioned in many later episodes) but not before getting quite a lot of impressive and impactful characterization.
• Sister Hannah, who appears in the last two episodes, is pretty interesting for running an Orphanage of Love and for being the first woman in the series who survived the Big Death as an adult outside of Typhoid Mary Meghan and some characters who rode out the virus inside the Raven Rock bunker.
• The Cargo Cult leader credited as "Man at Pole" in "The Long Road" only has one short scene and does little to affect the plot, but is well-liked for providing a highly memorable bit of levity and Worldbuilding when he tells Jeremiah that his congregation is "waiting for a call".
• Thunder Mountain scout Shashona only appears briefly in "Man of Iron, Woman Under Glass" but is well-remembered for having some hilarious quips and playing with the Magical Native American trope in interesting ways during his screen time.
• Faux Affably Evil Godhood Seeker and Tragic Villain Michael (Jason Priestley), from "And the Ground … Sown With Salt", is often considered one of the best Villain of the Week characters in the show.
• Michael's girlfriend Julie is considered to be another highlight of "And the Ground … Sown with Salt" due to having an expressive range of facial expressions and eventually getting some Neutral No Longer Silk Hiding Steel moments in the climax.
• Claire, the poetical woman who wants to sail to Europe and see if anything is left there in "To Sail Beyond the Stars."
• Eddie, the Knowledge Broker who collects $100 bills, and his contact William (a witness to the Burners' atrocities), both of whom also appear in "To Sail Beyond the Stars".
• The pregnant girl from "To Sail Beyond the Stars" never even gets a name, but her powerful interactions with Kurdy are compelling and memorable to many people.
• Rickie from "City of Roses", Kurdy’s childhood neighbor and friend, only appears for a few minutes to help Kurdy put some demons from his past to rest, but she makes a powerful impact in her brief screentime due to being a kind but edgy Caring Gardener.
• Chloe, the colorfully dressed woman selling worms and tarot fortunes in "City of Roses", makes the most of her one scene.
• Major Quantrell from "Firewall", due to him really moving the Valhalla Sector Story Arc forward with his presence, being Majorly Awesome in a creepy and ruthless way, and last but not least, being played by Michael Rooker.
• Talia, Tommy, and Beth, the three main kids at the colony in "Red Kiss," due to their strange but earnest beliefs and Badass Adorable moments in the climax.
• David (Alessandro Juliani), the head pilgrim from "Journeys End in Lovers Meeting", is a pretty thought-provoking character for his insightful yet enigmatic speeches and the eerie Maybe Magic, Maybe Mundane conclusion to his arc.
• Naomi and Elayne, the seperated mother and daughter in "The Touch", both make a strong impression on the fanbase for getting some of the biggest Tear Jerker moments of the episode, as well as a good awesome moment apiece.
• Michelle from "Mother of Invention," due to being a no-nonsense faction leader and Almighty Mom who nonetheless has some interesting chemistry and history with Jeremiah and has a surprising passion for old artwork.
• Edgar, the young man from "Out of the Ashes," who is protecting a library from book burners despite being unable to read.
• While "Ring of Truth" is considered to be one of the weaker episodes of season 1, three characters from the episode (Tai the elephant, circus performer Gregory, and Gregory's daughter China) all have a decent number of fans.
• Wylie, The Bunny-Ears Lawyer Conspiracy Theorist from "Things Left Unsaid Part II," who sheds light on all of the seasons' unexplained mysteries in a dynamic, methodical, and engaging fashion that provides a lot of help for the heroes.
• Sheila, the approachable but pragmatic settlement leader from "Crossing Jordan" who is also the first notable African-American woman to be in charge of a town since Theo, back in the pilot.
• Dr. Frederick Monash, the Sole Surviving Scientist of the Army of Daniel, gets some memorable Action Survivor, Defector from Decadence, Nice Guy, and Mr. Exposition moments in "The Face in the Mirror".
