In Big Willy Unleashed, Blasto made Crypto fail his assassination missions by killing the final targets before Crypto with his Ion Detonator. Blasto did that first in Harbor City, Fairfield, Fantasy Atoll, and Vietmahl, where he was caught by Crypto. When Crypto was about to kill him, Natalya called him and told him everything: after Crypto tampered with her DNA so that she wouldn't be able to resist him and cloned her, Blasto was born, but he had a certain hatred toward his father for abandoning him. Crypto started to act like the father he should have been years ago and Blasto left. Blasto left behind an Ion Detonator Bomb at Crypto's feet, which Crypto responded: "That Son of a--!" before it exploded. It was unknown if Blasto returned again in the future and reunited with Crypto in order to become a family, as it was detailed that Natalya died as her clone body could only lasted four years in Big Willy Unleashed (once again another time error as she would have been dead long before this happened).
Blasto was half Human and half Furon. He was very tall, had bright blue eyes, brown hair that was shaped like Natalya's (Crypto mentioned that he had his mother's hair), and a high pitched voice. He carried an Ion Detonator and flew on a Jetpack. Blasto acquired those when he asked Natalya for them. Natalya took them from Crypto, gave them to Blasto, and thought that Blasto was reaching out to his father when he really tried to kill Crypto out of anger.
