"it's *a* coffin,there is *a* name engraved on it 'Chara'." "you called out *their* name" "name *the* fallen human"

-the narrator refer to Chara as third person/someone else,in naturel/pacifist

undyne is *thinking* about her friends" "papyrus *realized* that he doesn't have ears"

-unless Chara can read minds,it would be impossible for them to have this information.there are also other things that Chara shouldn't be able to know,yet the narrator does such as:

1-the stats and the effects of all the items

2-the name of all the almost all the monster.

-the narrator says thing like "No data" which implies that they are an AI,or part of code of some kind

-why would Chara be helping a HUMAN of all things?

-Chara was self-aware BEFORE you fell "it is as comfortable as it looks"

Chara was feeling discomfort in the coffin that they ware removed from before you fall, meaning that you DT is not what awakened them and thus don't have to be stuck with you

-sadism in an average person starts at LV8 (you can see this by punching mad dummy) while Chara say "that was fun let's finish the job" at LV4

-you can reach LV15 in naturel but you wont get any red text,that shows Chara communicating with you because you spared someone and thus they can't fully eradicate the enemy and they also can't kill sans and get you to LV 20 and thus they can not realize (achieve) the purpose of their reincarnation that being power and eradicating the "enemy", giving them no reason to cooperate with you, you are a "failure" to them,that is supported through the lines "The comedian got away.failure" "Strongly feel [?] are left,we shouldn't proceed yet" they FEEL how many monsters are left somehow?they have a demonic sense that tells them how many living souls are left? tell me how can they do that if they are normal human kid?

-most of the "evidence" this theory has can be debunked easly

1-the "dirty joke" that you told to washowa is made by YOU,not Chara.

2-the narrator is NOT complitly silent in toriel's and Asgore's fight,"Asgore's HP is low" "Knows what best for you" "Asgore attacks" "You told Asgore that he had killed you once before. he nods saddly"

-Chara speaks in complix and overly dramatic deluge,while the narrator speaks normally.

-it's implied that Chara is SOULless

1-they can take the SOULs if their own spesice,something only SOULless being are able to do.

2-DT\LV or what ever freed them from their tomb and COMPELTLY revived them, can only revive conciousness,not SOULs.

and as we see with Flowey,SOULless beings are unable to feel sympathy.

-bosses die in one hit genocide because monsters get damaged more depending on the intention of the attacker,you might be saying that this is just because the LV you gain,but nope,again you can reach LV15 in naturel but you wont be able to OHKO anyone,while in genocide you do that by LV4, Chara's presents is required to do that, their hate is what help you kill them,they hate every single one of the bosses, possibly for the fallowing reasons

-toriel: for replacing them with another childe................ 7 times,that's the same way flowey feels,if you checked a certain echo flower after passing through it you will hear(read) this:

"Where oh where could that child be...? I've been looking all over for them...

Hee hee hee. THAT'S not true. She'll find another kid, and instantly forget about you. You'll NEVER see her again." [Final flower field, crossed through and then backtracked to the second flower, if Toriel was spared]

2-Papyrus:for being "forgetful"

3-monster kid: for being in their way

4-mettaton:for defending humans

5-sans for being so hard as shown by their facial expression if you reset after beating him

6-asgore for not using the souls to eradicate humanity

7-flowey\asriel:the same reason they call you a failure,because asriel failed them which also cased them their life.
