Sunboy's take on Blackheart was the earliest version to exist. It takes after Marvel Super Heroes. It contains gameplay accurate to said game, even with the infinity gem system present. As an added bonus, it also has a new Hyper involving Shuma-Gorath, as well as a Hyper that wouldn't appear until Marvel Super Heroes vs. Street Fighter.
Sunboy's version of Blackheart is based off Marvel Super Heroes, and as such, has its moves from said game. It even manages to have the infinity gems from said game, being activated by Ⓢ. These are:
Mind: Blackheart regains Power for eight seconds.
Power: Blackheart's Attack increases for six seconds.
Reality: Blackheart's Attacks spawn projectiles for five seconds.
Soul: Blackheart regains Life for seven seconds.
Space: Blackheart gains Super Armour for eight seconds.
Time: Blackheart's speed increases for six seconds.
Blackheart is generally a slow character. However, it more than makes up for it with its brute strength, along with its unmatched range (partly due to its size). Its Ⓩ and Ⓒ also spawn demons that attack or latch onto the opponent, possibly draining Life.
It has a rather unchallenging and easy A.I, considering what it can do. Most players can easily beat it.
