Ivankov seems to have a close relationship with his leader, Monkey D. Dragon, and is a loyal follower within the Revolutionary group. In fact, Iva picked up on Dragon’s habit of staring at the direction of East Blue when the wind blows, stating that Dragon may be homesick. However, while he knows this much, he seems to know little to nothing about Dragon’s family, until his son Luffy speaks out. Even when they rescued the people from the Grey Terminal, Iva had no idea that Dragon was born in Goa Kingdom.
Ivankov’s sense of camaraderie covers to the point where despite being a prisoner, his loyalty remains to the degree where he appears to be under no belief that Dragon has abandoned him. Ivankov has even stated that the only reason why he still remains within the Great Gaol was because he was merely biding his time, waiting for the right moment when Dragon will strike again, only then will 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.
