After Rewatching Both Steel Troops Films, I Think I Understood Riruru/Lilulu Better.
This isn't intended as a review of the movie or an argument about whether one version is better than the other. It's simply my attempt to analyze Riruru's character arc and explain why my perspective on her changed after revisiting the films. (This is a broad character discussion, not a detailed comparison of every scene in both films.)
Riruru was introduced as an undercover scout from Mechatopia. She apparently tricked Nobita, built the invasion base, and truly believed humanity should be conquered. She wasn't simply evil; she was the product of an unemotional empire centered entirely on interstellar conquest and enslaving organic life.
Then her perspective started to shift.
Nobita helped her without expecting anything in return. Shizuka cared for her despite Riruru's attempts to kill her. Pippo's changed view of humans and the kindness shown by the humans gradually challenged everything she believed about humanity.
Her transformation didn't come from just one person; it resulted from experiencing compassion from those she had been taught to hate.
For me, the moment that defined Riruru was when she pleaded with the General to stop the invasion, knowing she could be executed for betraying Mechatopia. Even after surviving that, she chose to travel to the past with Shizuka and help complete the scientist's reprogramming, fully aware that doing so would erase her own existence.
She willingly sacrificed herself for a world she had only just begun to understand.
To me, what defined Riruru most was that transformation: from an undercover Mechatopian spy into someone who willingly gave up her own existence for the very world she had once been sent to conquer. That is why now I see her as a spy who became a saint through self-sacrifice.
After reflecting on Riruru and comparing her with other Doraemon movie characters, I reached another personal conclusion.
I don't think there has been a greater act of unconditional self-sacrifice in the Doraemon movies. There are other memorable sacrifices, like Buggy's and perhaps Fuko's, but they feel different to me. Fuko had formed a deep bond with Nobita and his friends and had essentially been created and raised by Nobita.
Riruru, in contrast, chose to give up her existence for a world she had only just started to understand. She had every reason to stay loyal to Mechatopia, yet she rejected everything she had been taught because she recognized the value of the lives she had once been sent to conquer.
If Riruru never returns in a future Doraemon story and she very well might not I think this sacrifice will remain the defining moment of her character.
One last clarification: this isn't meant to start a "Riruru vs. Shizuka" debate or suggest that one character is simply "better" than another. My point is only about this specific act of self-sacrifice, not about ranking one character above another. I posted a while back about how I wasn't totally sold on Winged Angels being the absolute best Doraemon movie.Now rewatching both versions more carefully, made me appreciate the story as a whole much more. Earlier, both films were already within my personal top ten Doraemon movie rankings. As I revisited the series, some of my earlier favourites, such as Three Visionary Swordsmen and Diary on the Creation of the World, naturally dropped a few places. As a result, both Steel Troops films—the 1986 original and the 2011 remake—have moved up in my personal rankings.
