A lot of this seems taking stuff out of context to give an upgrade, or trying to take the most impressive interpretation of a feat.
Her throwing a spear at a table does not make her a "signature expert". She showed even less (read none) skill with the others, and it's not really implied that she eats with them other than having that stuff in there. She can have it for her training with Asgore, but none of the reasons you gave.
That isn't telekinesis, it's magic that can float. There is no one object she is controlling, just her magical energy. And adding it changes absolutely nothing, nor would it make her profile more clear... and for the matter, she doesn't even manipulate them after throwing them.
Rage Power is just a no, she just gradually stops holding them. When she gets angry because you fail to block her first attack it doesn't get faster until she decides to stop being theatratic.
Power Null is just a baseless assumption.
"Erase constructs"..? She throws a fireball at the flower, it gets blown back, and then starts stalking you through the game until the ending.</p>
That's not heat manipulation... that's fire manipulation. Because fire... is good for cooking.
Toriel might have the inventory, but assuming she got yellow mode, which is worse then her normal abilities regardless, or a jackpack, is no fair because the latter two were made for the Mettaton farce.
Reading books is fine, but she had over 7 children and always wished to be a teacher... I don't think she just made the curriculum on the fly.
The age is a no. The turtle is describing the delta rune, not how long the two were alive.
Asgore is superior the other monsters, not fighting him being a mercy is Undyne being theatratic.
The humans are completely unknown in power, so using an off-screen fight with them for tier justification is a no.
Flowey without violence has 19 ATK, obviously he couldn't beat a guy with 80 of it. That's not a reason for scaling when Asgore is superior to monsters stronger that Flowey.
That is not heat, it's fire manipulation.
Snowdin's ice isn't that cold, Undyne feeling cold doesn't mean it's any colder than real life places during winter while snowing (she had no heating clothing, let alone fur like Asgore), and the hotland thing is a gag made because Tobi was too lazy to remove the snow.</p>
No Ice Resistance for Papyrus, either.
Pretty damn sure the EMP was a bull because she controlled the whole thing from the beginning.
The noodles are in her fridge, they are no more standard equipment then the three plates of chicken I have in my own.
Alphys doesn't scale to Ghaster... at all.
She already knew the answer to all the questions except the last one that Mettaton asked to catch her off-guard.
She was behind Mettaton, and I'm relatively sure he was aware of it, too.
The saving part is them overwriting Asriel's own... and it's literally stated to be impossible to do, too.
Becoming a bodiless soul isn't immortality, and they could only act after being absorbed and not before.
No to Empathic Manipulation. Froggit is the one silly, and trying the same with people that are always serious is impossible.
Act failed to calm down quiet a few people.
The Faded Ribbon claims nothing about bloodlusted monsters.
That isn't dream manipulation. That's at most subjective reality, but more creation... limited to healing items to boot.
Ignoring that frisk passes the whole game possessed by the player, and Chara wasn't trying to manipulate them back then.
Claiming immunity to a power because the the energy can't be created artificially is a horrible NLF. Characters unable to copy tier 2 stuff will obviously be unable to do so, but anyone that can will easily copy DT.
That's not telepathy.
That is not Clairvoyance, it's basic observation. And the vision about Chara..? That's because they absorbed her consciousness.
Those are extrasensory senses. They are also taking the game trying to convey your achievement and a gag too literally, but I digress.
Walking for a few miles with a wounded child instead of any of the adults on the way helping them is not a reasonable assumption.
The skill in beating Asgore was "dodge and hit". Sure, dodging danmaku is a thing, but fighting skill isn't. Asgore killing six children just means they were not the greatest fighters. The other stuff is gags (talking through wriggling) or just unimpressive (the core wasn't that complicated, and doing the opposite of what Alphys told you was a great way to find the way.)
That isn't durability negation, it's stat reduction.
She is a humanoid spider staring at someone while licking her lips. The dude was intimidated into buying it, not convinced.
That is not power null, you're just unable to move faster when you can't move at all and even your souls is restricted by threads.
She doesn't fight much personally, and several of the turns are her spiders attacking while she does nothing.
A featless author avatar with no real effect on the story shouldn't be added at all, but whatever.
The gets stronger is a gag.
That wasn't the dog itself. That's just another dog prepared to be an explosive.
You won't give it duplication using a deltarune promoting trailer.
Monsters are weak susceptible to feelings to begin with. Regardless, this is Genocide Frisk, not Chara.
