With the breakout collaboration between Ubisoft and Nintendo set to return with Mario + Rabbids Sparks of Hope, the sequel will introduce some significant changes with its titular Sparks. Taking heavy inspiration from Super Mario Galaxy, Mario + Rabbids Sparks of Hope will see Rabbids and Luma fused to form "Sparks" that appear to be integral to the game's plot and mechanics. Sparks of Hope will see Mario and other fan-favorite characters return alongside newcomers like Bowser and Rabbid Rosalina, all venturing across the galaxy to save the Sparks.
