Or the electro-beast girl is just a hothead. That's my impression. Pairs well with resident ditz badass Shion, as illustrated.

The other beast nation people are much more cool headed. The knives guy was ordered to fight Youm, and both were kind of reluctant until they started going at it and got engaged in their fight.

Snake lady has just been cool and calm the entire time.

Overall, I'm fond of Tempest's demeanor: Let's try to be friends, and trade is best (we'll build the road for free). But if you're going to be an ass about things, repeatedly show disrespect, you're gonna get beat up. If you attack, you're just 100% going to die, because that's not cool. Their "diplomacy" is Youm's group spreading full on propaganda about how friendly and non-threatening they are.
