Crosteau is highly protective with nature (specially the Ocean), and he is the self-titled "Lord of the Sea". He is arrogant and cocky about his business and machines, and seems to know a lot about hijacking frequencies (as shown by his capacity of eavesdropping Crypto's communicator frequency). During battle, his speech is almost poetic in manner of speech, as he describes the battle as a documentary. He later recognizes that he was being used and asks for Crypto to apologize him for condemning his species.
