Jackson and 🕷️?
Their biggest fear is Ollie getting hurt or killed. He cares for him. Mundane fears would be people sneaking up on him, it's mundane because the only reason he is afraid is being of Maya's powers and hates being the butt of a joke. Also, funnily enough, he's scared of ghosts, again because his friend loves to traumatize him. Scared of the dark, scared of bugs, which is funny since he is a football player.
Isa and 🔪?
They do not act well. They blame themselves because they are able to create illusions and distort reality, causing them difficulty distinguishing reality and illusion. So when they get hurt, at first they blame themselves for allowing harm to come to their loved ones even in an illusion. When they realize it isn't an illusion however, they lose their damn mind. They will make your life a living hell, manipulate your perception of reality until you can't distinguish the two, and if your lucky, their friends will stop them before they get that far. BTW, the scariest thing about this character is that they're one of the few to actually have a separate costume and name for being a vigilante, meaning they can do whatever they want outside of the law, and they won't get caught. So yeah, not calm.
Arial with 🍓!!
This one is very easy because, since she is an undertale character, they don't have plants. So the answer is, none. However, I think she would love fruit when they get to the surface, I just get apple vibes from her tbh.
