For the SoniKoro 2024 collab, a merch-only variant of this costume appeared, first revealed as part of Japanese pre-order bonuses for Sonic X Shadow Generations, rendering her hoodie in the style of Shadow the Hedgehog, while her eyes have turned red and her hair black (referred to as Shadow Korone, or ShadKoro). Her black hoodie is accentuated with a fur-trimmed collar to match Shadow's fur tuff on his chest, and she's also seen wearing black shorts, unevenblack thighhighs, and Shadow's white and red hover shoes. The design would later be used for a collab cafe event.
