Hello everyone. In Impel Down we see Crocodile tell Luffy to free him if Luffy wants to escape. Luffy says no, but Ivankov assures him that Crocodile cannot do anything. This is because the two of them met when Crocodile was a new pirate, and Ivankov knows something that Crocodile does not want to be shared.
What does Ivankov know about Crocodile?
I have three ideas
1-Crocodile was a female and Ivankov changed him to male 2-Crocodile was a slave to the Celestial Dragons and didn't want anyone to know about it 3-Like Doflamingo, he wants to kill the Celestial Dragons
What do you think is a good reason?
