You know how Flowey’s favorite “character” is Papyrus?

No one ever talks about Chara’s favorite, and BOY do they have one.
Who’s the one monster that they never disrespect, no matter what route you take? The one who’s death they lapse into almost complete narrative silence about, other than Toriel and Asgore? The one who always, ALWAYS, has the title of the Heroine? 

It’s Undyne. Undyne is Chara’s favorite, and that’s not all. 

Think about the similarities between Papyrus and Asriel. Both are kind to a fault, and would never kill. They stick to their beliefs, even when it meant their own deaths. They cared about their siblings, and pushed them to do better.
I think Flowey picked up on that, and that’s part of the reason why he liked Papyrus so much. It was a reminder of what he lost.

Now Undyne. 
Undyne is goal oriented. She is willing to kill if she believes it is for the greater good, and she ALWAYS holds people accountable for what they’ve done. She’s the first person to call you out on your kills, and all of her pursuing and attacking you is because she’s trying to free monsterkind. You cannot befriend her if you’ve killed one of the people she’s sworn to protect, and that’s literally everyone in the Underground! She is the protector of all monsters. And that includes Papyrus, who she won’t let into the guard. Papyrus, who she tries to protect and guide away from his dreams because she knows about a harsh reality that he hasn’t been exposed to- or willingly chooses to ignore. Guards sometimes have to attack. Guards sometimes have to kill. And the people you protect will depend on you to make that choice, however hard it is. She is, by all counts, a rude, crude, pushy, impatient, and stubborn person. … who is undeniably a hero.

Undyne is everything Chara would have aspired to as “the hope of humans and monsters.” She isn’t the best person… But it doesn’t matter, does it? People still love her. She can still protect what she has, and exacts justice no matter what, even if that means sacrificing herself in the process. That’s something that Chara would have looked up to, especially given that they tried to do the same thing, however fucked up their process got. 

Papyrus and Undyne- Asriel and Chara. They’re sorta parallels, aren’t they?
And you can learn a lot about their personalities from their “favorites,” because honestly, who doesn’t have a fav that we see ourselves in?

workin’ hypothesis: Flowey and Chara’s “favorites” reflect their ideals in life, or whose characteristics they shared or aspired to. I’m willing to bet both.
