This is a muscle growth series focusing on characters from the entire universe of Sonic the Hedgehog, including the less known ones. Baker the bull ghost here, for we know, is the merged form of two white ghosts Su and Uh, but  BackyardGameboy wanted the fully-merged Baker to undertake the muscle ghost with no mention of those two ghosts.

Description:
Nixus the Echidna, no longer his original self Ixis Naugus, and his new allies of four evil muscular minions (specifically Pearly the Manta Ray, Princess Undina, and the two dolphin brothers, all who were fleeing refugees from Northern Ocean) continued pursuing the convoy that held the rest of the refugees until they lost track of the latter group somewhere around the Adabat islands. While his fellow minions were happily obliged to search for refugees by swimming, Nixus anticipated that they could also be hiding the aforementioned islands, even deeper in the jungles.

To help make soul searching easier, Nixus used his own magic to summon a ghost, a powerful yet ordinary one, and there came one named 'Baker' in form of a green bull, whom Princess Undina once recognized, but the bull ghost happened to be literally one entity with just one mind, not the two white ghosts she was more familiar with. Nevertheless, Nixus took opportunity to use the red strangely-carved stone turn the genuinely confused ghost into be a bigger brute force, not to be trifled with neither to be escaped from so easily. Much to everyone's surprise, even the ghost succumbed to the power of the glowing stone, but Nixus took no chance to gaze upon him for too long, as he commanded Baker to soar around and forcefully grab any hiding refugee (or even an unaware local) the Adabat islands one by one, while he allowed his fellow minions to do the searching in any way they pleased. And yes, not even nearby locals were spared from the wrath of the corrupted hunks, as they fell before the overwhelming power of the red glowing stone.

Sealia Seal and the corrupted Arctic Freedom Fighters would later join Nixus' search party, through both land and sea, as no one else could count how many refugees were holed up in Adabat. In the middle of the said search though would Nixus admit to be Ixis Naugus who escaped from New Mobotropolis but he was now a changed Mobian, and Guntiver the Arctic Wolf, having been called to look for Ixis Naugus on behalf of the Council of Acorn and having recognized the changes in Nixus, would later contact Nicole the Holo-Lynx about the purple echidna's misplaced adventure, much to her grim delight.
