This gives me some ideas, and with multiple cosplays as well.
I'll be debuting Sam Fisher from Splinter Cell if you want some night time stealth action. I think it would probably be best if I had someone has a generic guard to take down or something...
And I will be cosplaying Yang from RWBY, and her fighting style (sans the fantasy stuff) is similar to what I've been formally taught.
I'm also going to be cosplaying Punished Snake (MGSV), Link in Goron Tunic (LoZ:OoT), and Marisa Kirisame (Koumajou Densetsu/Touhouvania) if you think you can use those.
