JOSHUA ISAAK, ScreenRant; Mephisto's Most Powerful Servant Got Marvel Sued by the Hells Angels
"Hells Angel, appearing in 1992, was named Shevaun Haldane and had quite a traumatic start to her stint in comics when Mephisto brutally killed her father. She was later trapped into serving the satanic villain, but eventually broke free of his clutches. Unfortunately, she couldn't break free of the Hells Angels lawsuit, which stipulated that Hells Angel infringed on their name. Surprisingly, Marvel acquiesced to the gang's demands and changed Shevaun's character name to Dark Angel...but that only landed the company in more hot water when they were the subject of yet another lawsuit.
In addition to donating over $30,000 dollars to charity, Marvel now had to change the name to Dark Angel. Alas, the name was owned by Hart Fisher's Boneyard Press for another comic. Boneyard filed suit and the house that Stan Lee built had a choice to make: either change the character's name yet again, or fold and cancel the publication of Dark Angel. That's the choice Marvel made, and in Issue #16, the Dark Angel brand was put to rest."
