Arbok is loyal, strong and brave and always does anything Jessie asks without hesitation. But it is also sentimental about harming its kind when it saw a bunch of Ekans caught by a poacher. It felt great sorrow about leaving Jessie forever when she told it to protect its fellow Pokémon. It is shown to be very emotional and will often show extreme sadness when it is separated from its trainer.
While Arbok has a strong bond with Jessie and cares for her deeply, it never views itself or any other Pokémon as bad guys, as shown when it was an Ekans in Island of the Giant Pokémon when it and Koffing refused to battle under Meowth's orders and told the latter that Pokémon only do bad things out of orders from their trainers.
Jessie's Arbok was most likely Jessie's first Pokémon. She got it as a Ekans for her birthday. Eventually it evolved into an Arbok because Jessie wished desperately for it to. It was later released to protect a group of Ekans from a Pokémon Poacher. When Jessie told it to stay behind and protect the Ekans while she, James and Meowth held off the Pokémon Poacher, it started crying as did James's Weezing.
