Toriel plays the role of "mother", in turns of shaping Chara, and we don't know who their human mother was.

But really, I don't think Chara took control at all until LV19. They did try to convince you to go Genocide, though. I have a hypothesis in the works as to Chara's true nature:https://undertale.fandom.com/wiki/Thread:151492 (It already finished how Chara was before they died with Asriel, and currently also has a separate hypothesis on what caused the fandom to split the way they did, as a result of my first attempt to analyze Chara from scratch [well, scratch plus what I built before back in pre-death].. )

We can ONLY play as the role of Frisk. We, the player, are Frisk. This is canon. I've proven this in #5 of my response.
