Here is an overview of the character, via western publisher NIS America:
From the Million Arthur series, Thief Arthur arrives and steals the show! Once long ago, she infiltrated Camelot to steal some of its legendary treasure, accidentally removed the legendary blade Excalibur, and became king! Her stubbornness gets in the way of showing kindness towards others as well. Now, she arrives in SNK Heroines: Tag Team Frenzy to swiftly kick, punch, and whack(!) her opponents before snagging their treasure!
