"Then leave it to Astro MK! That's me!"
— Astro MK after Alisa Bosconovitch says that no one can awaken Asuka Kazama.

As the Nintendo GameCube, Astro MK, better known as Astro, is one of Alisa Bosconovitch's close friends. He is known for shooting 80 millimeter optical discs out of the top of his body. These discs are used to awaken the female Rocko franchise characters. When he used these on Asuka Kazama in his premiere episode, she woke up, looked around, and went back to sleep. The second time he did this, Asuka kept snoring.

Blake Clark, Slinky Dog's Toy Story 3 voice actor, is Astro's voice actor throughout Alisa's Adventures in Rockoland.
