Kosofftro's signature characteristic was his 2 hanging buck teeth over his lower lips. He wore a broad-brimmed hat, matching shirt, trousers, and shoes decorated with arrow motifs, and wrapped his limbs in bandages. He was also seen carrying a sword.
Kind and cordial, he informs new alliance members to remember his name if they want to return to their base.
Greed Island arc
Kosofftro sits in a forest located near the base all day, so that people can use him as a checkpoint and reach him with "Magnetic Force" and "Accompany" cards, thus allowing members to go to the base. Jispa uses an Accompany card on himself and the new recruits to transport them to Kosofftro. Arriving at Kosofftro's location, he welcomes them and introduces himself.  Because Genthru attached his bombs on all of the members of the alliance, it can be assumed that Kosofftro is dead.
