Roberto da Costa was a young, wealthy Brazillian when his mutant power attracted the attention of Donald Pierce. After a failed kidnapping attempt Charles Xavier sent his New Mutants to help da Costa defeat Pierce. Da Costa later joined the New Mutants, under the code-name Sunspot.

Note: It is necessary to use parts from Cannonball in the New Mutants Box Set to create the uniformed version of Sunspot seen in the 'Alternate' images.
