Gonna take a moment to talk about the DC Cinematic Universe and MCU here. Marvel have yet to put together an anti-hero group but considering how cohesive they've made their universe I feel like there's only a slim chance that it'll flop. DC however created Suicide Squad and introduced characters that haven't previously had their own films (focusing on the cinema first). The Joker and Harley Quinn are the most famous out of the group and even then I can't recall Harley featuring in a film in recent years. As much as I loved Suicide Squad (for the plotless chaos it was) the vast majority of it was backstory, we found out bits about each member and then arguably one of the most interesting (Katana) we were told hardly anything about. She just spoke to her sword and threatened people... Similar thing has happened with Justice League. We've had multiple incarnations of Batman and recently Wonder Woman (which was incredible and I sobbed) and also the Flash TV show but we know nothing of Aquaman and Cyborg...HE'S A TEEN TITAN.
For this reason I really wanted to know more about Katana from the little description we got I was immediately hooked by her character and when I saw this graphic novel I thought it would be exactly what I wanted. A look at how she got to where she is. It's not. It follows her on a journey to a place called Markovia to complete a mission of some kind. As much as I love anything superhero/anti-hero this fell a little flat for me. I can't really remember anything about the graphic novel which is never a good sign and I don't feel as though it furthered her character.
I remember enjoying what I read but it wasn't anything mindblowing. The art was pretty and I liked the colour palette but everything else was a little meh. With, from what I remember a very odd plot.
