SYNOPSIS:

In a vibrant city teeming with futuristic technology, Astro Boy, a young robot with incredible powers and a heart of gold, is on a mission to protect humanity while uncovering the mysteries of his own past. During a routine patrol, a malfunction in a nearby experimental energy reactor creates a dimensional rift that unexpectedly transports him to the lush and whimsical landscape of Green Hills—a world dominated by speed and adventure. Meanwhile, Sonic the Hedgehog, the fastest creature alive, is racing through Green Hills, enjoying his freedom and keeping an eye on his friends. When Astro crash-lands near him, Sonic is initially bewildered but quickly realizes that they share a common goal: to thwart the nefarious plans of Dr. Robotnik, who has learned about the dimensional rift and aims to harness its power to conquer both worlds.
