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.
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.
