A fan made mascot/personification of the fictional company Arquebus Corporation from the game Armored Core VI: Fires of Rubicon, originally designed by washi01 and her husband in her tweet.
Named with a portmanteau of 'Arquebus' and 'Boy', it is a humanoid figure that wears the arch section of the letter A over its head like a colonial powdered wig. Usually depicted fist-fighting against Baltaro, the Balam corporation counter part.
