Need advice on villain name, aspiring comic book writer/artist

So I want to make comic books, and I made my own superhero comic, and I already have more than 20 villains that have depth and more. One of my villains is one of those evil versions of one of my heroes. The hero is called RedFox and I wanted to call this Villain Dark Fox as his suit is modeled after a black melanistic fox. I gave him fire powers but now Im worried people will think it’s not a fitting name and I should call him Firefox instead, but I’m not sure I like that name. I think Dark fox is more fitting as he is an anti of my hero and sees my hero as his arch enemy and opposite. I’m having difficulty making a decision so I came here to ask you because you all most likely know about comic books and what makes a good comic book character. What do you all think?
