Emporio Ivankov is the “Queen” of the Kamabakka Kingdom and an officer of the Revolutionary Army. After the destruction of Baltigo, the Revolutionary Army moved their base of operations to this island.
Ivankov seems to have a close relationship with his leader, Monkey D. Dragon, and is a loyal follower within the Revolutionary group. Ivankov apparently understands Dragon’s habit of looking at the direction of East Blue whenever the winds blow, as though he is homesick. However, Ivankov had no knowledge of Dragon’s family until after he met Luffy years later, which led the commander to protect him at all cost. It is unknown how Dragon met Ivankov.
Ivankov’s sense of camaraderie covers to the point where despite being a prisoner of Impel Down, his loyalty remains to the degree where he appeared to be under no belief that Dragon abandoned him. Ivankov even stated that the only reason why he remained within the Great Gaol was because he was merely biding his time, waiting for the right moment when Dragon will strike again, and only then would he break out of Impel Down and join Dragon by his side, a notion that got accelerated upon learning that Luffy was Dragon’s son, and the assumption that Ace was as well.
Following the end of the Battle of Marineford, Ivankov is contacted by Dragon and they caught up. Ivankov remarked on Dragon’s family ties being revealed while Dragon expressed surprise that Ivankov protected his son and sounded grateful to him.
