I'm searching a shorter way to say "Something that will be fought". I'm actually creating an app and I'd need it as a title for a field. So it needs to be short and relevant, but I can't find another way to say it. Thank you.
EDIT : It's a living thing that will be fought, like a person.
EDIT 2 : To be clear, the user will choose a monster to fight. So I'd like to write "Monster that will be fought" in a shorter way, but not just "Opponent", as it's too vague. I hope I'll be understood now, sorry.
