Sonic and Shadow had been happily dating for two years, both now 19 and feeling comfortable in their relationship. To celebrate their love, Sonic threw a festive party at their home, inviting friends for a night of laughter and games. The lively atmosphere was filled with colorful decorations, delicious food, and cheerful camaraderie. Sonic charmed the guests with his antics while Shadow observed, content in Sonic's presence, still adjusting to the social scene.

However, the celebration took a disastrous turn when Eggman appeared in his flying contraption, disrupting the fun with a menacing machine that fired a beam at Sonic and Shadow, pulling them away from the party before anyone could react.

As confusion settled, Sonic's friends quickly regrouped. “Why did Eggman only target them?” Tails asked, and the group exchanged worried glances. Determined to understand Eggman's motives and rescue their friends, they devised a plan to infiltrate his base.

In the center, they found a crib housing a small baby—a perfect blend of Sonic's and Shadow's DNA, wrapped snugly in a blanket. The shocking realization that Eggman had created life hit them hard.
