Santiago is a notorious criminal masquerading as the iconic video game character Sonic the Hedgehog. In a surprising twist, he encounters the genuine article (the real Sonic) during the musical showdown featured in the song: Forces. As Sonic confronts his malevolent doppelganger, who wears a disarmingly innocent smile, he senses something amiss. Sonic realizes he must confront his imposter decisively to reclaim his rightful title as the true Sonic through an epic rap battle. Armed with his guitar, a nod to the short-lived 1999 cartoon Sonic Underground, he demonstrates his authenticity by playing it throughout the song. In contrast, the imposter Sonic, who merely holds a bright red microphone, lacks the same guitar, revealing his true nature despite his seemingly friendly appearance, as they both sing until the very end.
