How much is the Dark Knight in Fortnite?

Excuse me, I'm curious about something. Could you possibly shed some light on the price of the Dark Knight in Fortnite? I've been hearing a lot about it lately and I'm wondering if it's something I should consider investing in, or if it's just a fleeting trend. Is it a limited-time offer or can I still acquire it at a later date? And most importantly, how much does it cost? Your insight would be greatly appreciated.
