Just some Undertale Headcanons that I’ve come up with through RPing here on tumblr or talking to friends on Skype.
~Yosuke has his power of Persona while in the Underground, however his powers are significantly weaker than they would be in the TV World. That doesn’t mean he’s a pushover. He can still fight it’s just not as potent in the real world.
~Yosuke cannot use his ability to escape the Underground, he is trapped there like everyone else. The only way for him to escape is to break the barrier or through some third? fourth party means.
~He does not have the power of Save and Load meaning he has one life and if he dies he dies.
~Yosuke will have his kunai on him, hidden under his shirt and will use them to defend himself, however he will never kill anyone. Knock them close to the brink of death yes, but murder no.
~Due to the nature of his powers he can help break the barrier without dying since the power of Persona is the manifestation of the strength of heart. But he cannot break the barrier on his own, or even come close to scratching it by himself. If he had help that may be a different story.
