It's like an entire legion of doom, but not! This is from the Marvel Legends Series 13 Bring On The Bad Guys Action Figures series. The Blackheart action figure includes a 32-page comic book, and a piece of the giant build-a-figure Onslaught.
Blackheart is the son of Mephisto, one of the many rulers of the Underworld and a frequent opponent of Earth's heroes. Like his father, Blackheart desires power above all else and has shown a willingness to go to great lengths to achieve it. This figure stands just under 8-inches tall.
