How Chara (if it was they) takes control over Frisk? It cannot work the same way as when Asriel, the monster, absorbed Chara's human SOUL - ''Frisk, when  and I combined our SOULs together... The control over our body was actually split between us. They were the one that picked up their own empty body... They were the one that wanted to... to use our full power. I was the one that resisted.'' - Asriel. This won't work for Chara/Frisk, because of: ''After all, a monster cannot absorb the SOULs of other monsters. Just as a human cannot absorb a human SOUL...'' ENTRY #7. Unless one of them is neither human nor monster, like in Flowey's case - We'll need a vessel to wield the monster SOULs when the time comes... What about something that's neither human nor monster? Entry #7, ''I've chosen a candidate... The first golden flower, that grew before all the others. I wonder... What happens when something without a SOUL gains the will to live? - ENTRY #8, I remember when I first woke up here, in the garden. I was so scared. I couldn't feel my arms or my legs... My entire body had turned into a flower!'' - Flowey. In this case neither human nor monster Flowey can absorb SOULs of six humans and every monster in Underground - see True Pacifist Route ending.

However, now comes this: In several moments throughout the Genocide Route, Chara temporarily disables the player's input and takes direct control of the Frisk:

 ...when the Frisk does not hide behind the conveniently shaped lamp... ...during the first encounter and puzzle with Papyrus, where the Frisk ignores Papyrus and moves forward independently. ...before the battle with Undyne, where the Frisk turns away, and then approaches Monster Kid aggressively. ''...in the Throne Room, where without any input from the player, Chara kills Asgore without hesitation. As with Flowey, several strikes are dealt if the player presses "ENTER/Z" a single time.''  - Wiki

If above is true and Chara really takes control over Frisk, that means:

 one of them must have absorbed other's SOUL so control over body can be actually split between them - see Asriel's story, SINCE WHEN WERE YOU THE ONE IN CONTROL? - Chara the SOULs must not be shattered or incomplete in order to stay self aware, to be operational - ''See that heart? That is your SOUL, the very culmination of your being!'' - Flowey Chara can not be a monster, they must be a human - ''Indeed, a human cannot take a monster’s SOUL. When a monster dies, its SOUL disappears.'' - Waterfall Ancient Glyphs, see Asriel's case, ENTRY #7</li> Frisk must not be a human - see ENTRY #7 and Flowey's origin, in addition: ''well, i'll be straight-forward with you. my brother'd really like to see a human... so, you know, it'd really help me out... if you kept pretending to be one - Sans to Frisk, Howdy! ... Erm... What kind of monster are you...? Sorry, I cannot tell.'' - Asgore to Frisk (I can tell =)</li> </ul> Conclusions. It is unlikely that exists some alternate, never mentioned form of taking control over body than absorbing one's SOUL. Moreover Chara, or basically <Name>, states that they was with Frisk from the beginning: ''Thank you. Your power awakened me from death. ... At first, I was so confused. Why was I brought back to life? ... You. With your guidance. I realized the purpose of my reincarnation. Power. Together, we eradicated the enemy and became strong. HP. ATK. DEF. GOLD. EXP. LV...''

Although Frisk being called human child, their current condition totally contradicts it. That small humanoid with strange yellowish skin, always closed eyes, who doesn't speak, doesn't have facial expression and body language (in comparison to legitimate human - Chara) is either very unique type of monster or just an empty vessel highly contaminated with Determination - ''<Name>... Your DETERMINATION! Somehow, it's even greater than mine!'' - Flowey describes Frisk. The vessel that has absorbed Chara's SOUL when they were in close proximity (see Flowey's origin), and that human SOUL is actually visible on the Bullet Board - it belongs to Chara.

It also means that there are actually seven humans and SOULs, not eight.<ac_metadata title="Is Frisk actually a human?" related_topics="Frisk"> </ac_metadata>
