Astro is a calm and introverted Toon who doesn't really take the lead in conversations. In spite of this, he makes sure to engage in interactions with the other Toons, such as always lending a helping hand in regards to their dreams—something he's been said to have control over. He enjoys peace and quiet, and is a bit high-strung in relation to anything interfering with those two things. Even so, he genuinely does care for other toons, but may unintentionally come off as standoffish sometimes.
