I spent about $15 on costumes. I got...
1.
Jeans 80's outfit with the short hair and the shoulder pads. Her ass looks great in this.
2.
Lokis classic first alt outfit with the helmet and armor. I later heard in the game chat that he sucks. lol. At least he'll look good.
3.
Cyclops new outfit with the long hair. It looks very unique and I also love the metallic futuristic looking bits on it.
4.
Starlords red trenchcoat alt. Man, this outfit looks so good. I havent even bought Starlord yet (I have over 1550 Splinters ready to go though), but I know he will be the kind of character I enjoy.
I was very tempted to buy Frankencastle as it looks really good, is really cheap and will likely only be available for a limited time. I already have 4 Punisher costumes though.
Also considering getting Rogues xmen outift. Her green and white default is arguably the ugliest costume design in the game and the xmen one does look really good.
Also I saw this...
Taskmaster must think he is some kind of dragon slayer (hiya dragon?). I love seeing small details on outfits that are rarely seen.
