Insights

Released in 2016 as a promotional polybag, Cosmic Boy (30604) contains an exclusive minifigure with character-specific prints, and its constrained distribution and retirement have left sealed examples scarce. Demand is concentrated among minifigure collectors, and secondary-character volatility tempers broad upside.

Set Facts

This minifig was included in the Justice League Cosmic Clash DVD/Blu-Ray as well as stand alone in a polybag.
Cosmic Boy is one of the founding members of the Legion of Super-Heroes along with Lightning Lad and Saturn Girl. This version of his minifigure is the New 52 version.

HelloBricks by Brickman

“With this Cosmic Boy Lego begins a new series of Super Heroes: Legion of Super Heroes”, founded in the third millennium by the philanthropist RJBrande and supposed to ensure the security of the United Planets. He will be joined later by the Lightning Lad minifigure, which... More will be included in future Target cubes, like Super Boy.”
