Hmm? I didn't say anything about liking BB, I just commented about the latest posts discussing what kind of characters would join an alliance with BB.
I never talked about age; I tried to convey the niche Rebecca was supposed to have. I meant "child" in the sense of a daughter of someone. Vivi was an independent character who was introduced way before her father, whereas Rebecca was introduced in conjuncture with her father. Their entire purpose was a focus on a certain family among the citizens of Dressrosa, alongside the overview on the entire history of the country (hence the references to the flashbacks); Vivi was a protagonist of that arc. Vivi's flashbacks served to develop her character, Rebecca's flashbacks served to develop the whole Riku family.
Again, they did not serve the same role, aside from being princesses. You're contradicting yourself, you're saying her role was to make Luffy fight the antagonist but then you something else had that role, which just further proves my point.
You're talking about her doing nothing from a reader's standpoint. As a character, we got all the necessary reasons to why she couldn't bear doing nothing. Even if doing nothing is what seems rational to you, you need to think about it from her perspective, as a human, which like all humans, can be overcome with emotions and make irrational decisions.
Just because she was afraid, that makes her a bad character? doing brave things while being afraid is actually very believable.
Again, she shouldn't even be compared to Vivi.–- Update From New Post Merge ---
I was analyzing Rebecca from a more literary standpoint, but whatever floats your boat.
I rarely ever see people bring that up that is why i posted it since that makes her worth having in the story lol.
