Blue Raspberry is the fusion of Raspberry and Blueberry and the current de-facto leader of the Healthy Fruits. Blue Raspberry is one of the last surviving Fruits in Stephanie's Fridge who joined the Healthy Fruits in the rebellion against the HomeStock Store, and afterwards assisted her friends in protecting the fridge and other surrounding area over the next few millennia. After Strawberry gave up her physical form to give birth to her daughter, Stephanie Shopper, Blue Raspberry took over as the leader of the group.
Though she is often the most pragmatic and straightforward of the Healthy Fruits , Blue Raspberry tends to act on intuition rather than seriously analyzing a situation, as often seen throughout the series. As the leader, Blue Raspberry is often the peacemaker of the Healthy Fruits, especially when Tomato and Grape start arguing. She demands utmost respect from the other Healthy Fruits and is not hesitant to berate team members should they refuse to follow an order.
Equable and mellow, Blue Raspberry is capable of remaining composed in most situations – this part is taken from Blue Raspberry. This is displayed in the episode, "The Isle", where Grape and Tomato were at a loss for words when they tried to explain to Stephanie why she was forbidden from fighting alongside them at the Vegetable Cart's landing. Blue Raspberry was the only Healthy Fruit who was able to effectively get their point across and convince Stephanie to join Athen's evacuation. She was able to remain strong and act practically despite the dangerous and uncertain situation.
Blue Raspberry demonstrates a fierce competitive spirit. This is best seen while she is playing Softball in "Fridge Competition", "Stephanie Tag" in "Keep Athens Normal" and arcade games in "Arcade Mania". Blue Raspberry also has a tendency to act in extremes, either maintaining her normally reserved nature or lashing out with extreme emotion, both of these personalities belonging to her two constituent Fruits, the passionate Raspberry and conservative Blueberry. Despite this, it should also be noted that Blue Raspberry can be seen with emotions neutral to these, but it is a rare occurrence.
While mostly level-headed, Blue Raspberry can still lose her cool. When Stephanie passed out after seeing Apple leaving the fridge in "G'Day and G'Bye", Blue Raspberry started violently shaking her, thinking, in her desperation, that violence might be the answer. Another example of this can be seen in "Smoothie Dinner" as she panics under pressure when talking to Connor's mother over the phone, leading him to claim that Stephanie and Connor had died while playing with swords. In "Stephanie's Dream", when Paul has been captured, she is constantly apologizing to Stephanie about how she should have told him about what was going to happen since the beginning.
Blue Raspberry was very excited when she saw them mix into Horned Limeon.
