For the Comic Book
- Base Breaker: Sam Alexander. While some fans have been willing to give him a chance, others don't want anything to do with him.
- Ensemble Darkhorse: Cosmo, who debuted in two issues of Nova's fourth series and was so popular he became a regular character in Guardians of the Galaxy.
- Fandom Berserk Button: Calling Richard Rider Ryder.
- Growing the Beard: Some fans thinks Sam's series is starting to get good thanks to Gerry Duggan's writing.
- Marty Stu: Some Rider fans accused Sam Alexander of this simply for existing despite the fact that by all logic he couldn't have his powers, since most of the Nova Force went missing with Richard Rider, along with the fact that his father was part of a super-secret bunch of special ops Novas that conveniently have never been mentioned or hinted at before. Others level this accusation because they perceive Rider's continued absence in favor of a rookie who just happens to be named after the deceased son of the writer who created him to be an abuse of said writer's privilege as a figure with a significant amount of pull within the Marvel publishing hierarchy.
- Memetic Mutation: "I pulled him inside out and saved the universe. What have you done lately, X?"
- My Real Daddy
- Dan Abnett and Andy Lanning — their take on the character forced everybody else to stop treating him as an inexperienced rookie.
- Gerry Duggan for Sam Alexander.
- Narm: Volume 5, Issue 29◊; the splash page on Sam's announcing Richard Rider's demise falls flat due to Baldeon's drawing on Sam Alexander's Nova form.
- Nightmare Fuel: The Knowhere story in vol 4 is all kinds of disturbing.
- Knowhere itself is pretty disturbing. A decapitated Celestial's head floating at the literal edge of the universe.
- The most recent version of Richard's heroic sacrifice in the Cancerverse shows that the Revengers version of Captain America cut off Richard's arm with his shield. Previous sighting of dismemberment in the Cancerverse have almost always resulted in the victim regenerating into a Body Horror.
- Replacement Scrappy: Some more ardent Richard Rider fans consider Sam Alexander to be one. Time will tell if Sam will be Rescued from the Scrappy Heap.
- Tearjerker: The death of Ko-Rel, along with all her friends, co-workers and associates, which all happens in the space of a few days.
- In Volume 5, Issue 29 of Nova, Sam Alexander announcing Richard Rider's demise to his parents. Richard's father just broke down after hearing both the news and seeing his helmet. Sam didn't take well on his delivery either.
- The Woobie: Jesse Alexander. Sure, he used to be a Centurion and a member of Supernovas but he didn't finish Highschool as a result and failed to adjust his life on Earth. Due to these failures and alcoholism, his son Sam began to questioned his story until he became the new Nova. Later, the former members of Adomax's Supernovas caught him and sold him as a slave to Chitauri.
For the Novel
- Incest Subtext: Prince and Ruby Red's relationship can start to look a little... iffy. Let's not forget that Ruby dies from anaphylactic shock after kissing her brother's corpse; apparently quite, erm, passionately, since she was killed almost instantly.
