Obi-Wan is the ultimate jedi. He's been in so many life-threatening situations and always remains calm about it. His sarcastic attitude is the best and in those situations, he jokes about things sometimes to whoever he's with or fighting. Like in The Clone Wars series, Obi Wan and Ventress team up to fight Darth Maul and Savage Opress. The whole time Obi Wan is throwing sarcastic remarks and jokes around with Ventress. For being enemies at one point, they surprisingly have great chemistry together.
