Core Frisk

CORE!Frisk is a fickle, enigmatic child who is unable to mentally grow despite their nigh infinite knowledge and wisdom. They frequently combine the behavior of an immature child and a wise adult, using eloquent words and bratty remarks within the context of a single conversation. While they are fully capable of mature behavior and most people's first impression of them is likely a reserved one, most are usually quick to witness Core's childish side. It seems that while Frisk wants everyone to take them seriously, they also don't want people to avoid them out of fear - therefore, they go out of their way to appear as non-threatening as possible. Despite this, Frisk claims that they never put on a deceptive act and simply behave however they feel like behaving.

Even though they're incredibly compassionate and supportive, somewhere deep down they believe no one understands things better than they do and may subtly treat everyone as such. This behavior tends to amplify the more they dislike someone, growing all the way into mocking condescendence - although most people are never going to witness this side of them. Above everything else, Frisk rejects the notion of sacrificing people's lives and well-being for things such as "greater good" or "creative vision" and doesn't take lightly for their ideals to be challenged; therefore, the people Core Frisk despises are those who wilfully hurt others for the sake of curiosity, advancement, or power. It is worth noting that if those people are simply misguided or despairing, Frisk WILL pour painstaking, unfathomable effort to help them better themselves and guide their path towards redemption. Ultimately, Frisk has a simple goal, and that goal is to help others.

It appears Frisk is afraid of sirens and firearms due to trauma caused by the war that plagued their childhood. They also dislike going underwater because their sockets drain the water and pouring it all back out is really uncomfortable.
