Henry Acorn, son of Nigel Acorn, is a bit of a unique anomaly in the Post-SGW Universe. Nigel had noticed Sonic was hiding a sort of regret in his eyes, and a heartfelt confession revealed Sonic had made Max a promise to continue the Acorn line in some way, even if things didn't work out with Sally. But with the world rewritten, not only was Sally not into him anymore, but Elias was gone as well, leaving Sonic feeling like he'd failed his promise.
While neither Sally, Max, or Elias, Nigel could feel that sort of strange connection, and decided to take it upon himself, letting Sonic impregnate him with a unique ability amongst Chaos Users, forming a bond with the hero.
Two decades later, Henry is the spitting image of the duality between royalty and wildheart adventurer. He's not afraid to flaunt his wealth (such as having his broken tooth capped in gold), but he vastly prefers the outdoors as well, fancying himself a bit of a safari man. He can also run pretty fast thanks to his hedgehog genes, though not supersonic speed. He also has a very sharp nose, and can track literally anything he's seen before thanks to an oak staff acting as a dowsing rod.
Henry adores his big half-sister Sally, and aspires to have her confidence, which he definitely lacks, preferring to run AWAY from danger rather than toward it. He also has a great relationship with his other half-siblings from Sonic's prior relationships.
