- Complete Monster: Mr. Titan is the first and worst executive of Black Satan. Once a suave criminal who quickly jumped into the opportunity to join Black Satan, Titan rose through their ranks until he became one of the Great Leader's Co-Dragons, supervising and overseeing the Kikkaijin on the field to make sure that they are successful while being cruel towards his own men; Titan is involved in numerous destructive operations, including but not limited to: tainting the school lunches of elementary school students with capsules of Tetrodotoxin; contaminating the water supply of a town with a chemical that induces homicidal insanity; and using a cacophonic sound to make adults kill children. When Titan gets his hands on the Gamma Bugs, parasites that are capable of killing their hosts, he tests their properties on a captive and makes the man strangle himself to death for fun, planning on spreading the Gamma Bugs over Tokyo to help Black Satan in controlling the city, and when that fails, Titan tries to assassinate a sheik to disrupt international relations. Recruiting Black Satan's strongest Kikkaijin to assist him in a plan to export poisoned food worldwide to kill millions and allow Japan to be invaded, Titan is killed after sacrificing a Kikkaijin in an attempt to kill Shigeru Jo. Revived by the Great Leader, Titan earns the enmity of his rival General Shadow for using dirty tactics to win, with one of his first plans after his return being mass-producing a bioweapon for Black Satan, forcing an innocent prisoner to inhale it. Defeated yet again, Titan proposes a handshake before he dies to show that he respects Jo, only to reveal that it was a trick to take Jo to hell with him.
- Franchise Original Sin: The "Female Rider Curse" (where female riders are killed off), although officially starting in Kamen Rider Ryuki with Femme, has roots in this series. There have been a few exceptions to the rule, but currently the number of exceptions is outnumbered.
- For what it's worth noting, the only reason Tackle stayed dead was because of the show's length. According to the producer, if Stronger had a standard run of 52 episodes, they would've brought her back - interestingly, if that was the case, this trope would still be played straight, except with a different issue fans complain about (bringing heroes who sacrificed themselves Back from the Dead).
- Harsher in Hindsight: Tackle's death becomes this when taking into account that her actress, Kyōko Okada, died young of a severe asthma attack. It's even harsher when you realize that Okada being asthmatic is the reason why Tackle does very few action scenes. In other words, most of her fight scenes barely qualify as such because of a condition that she would ultimately die of, and her character's only real victory in a fight ended in said character's death.
- Heartwarming in Hindsight: Now that Shigeru Araki, Jou's actor, has passed away, some want to assume that his character did so as well, despite his continued teamup appearances. In other words, now Jou and Yuriko can be together in Heaven.
- It Was His Sled: Yuriko's death. Doesn't mean it's any less impactful.
- The Scrappy: Yuriko, at least at the time of the original run, for being a female superhero in a show featuring a male superhero.
- Special Effects Failure: Even among tokusatsu shows, Stronger was infamous for having a shoestring budget, with a lot of monster costumes designed created by "dumpster diving" and hot-gluing parts together. Even Stronger himself wasn't immune, as his costume received a rather noticeable crack on the stag horn, which could be pointed out when the costume was reused for Skyrider.
YMMV / Kamen Rider Stronger
