Ask HN: How do you name your teams?

Hi, We have two software development teams and temporary names are X and Y at this moment. But we'd like to change them to something less competitive. Right now it looks like the Y team is the secondary to X team even though it's not the case.

So, we can't use letters (such as A and B, or X and Y), numbers (1 and 2, I and II, etc.) and Greek alphabet (alpha and beta which is similar to A and B). That leaves us the colours, animals, plants, and planets. We're not all men or women in any of the team. As a result, we can't also use Mars and Venus or Blue and Red/Pink kind of names too.

How would you name your teams in this situation?

P.S: If you are going to give team name examples, please be careful that they shouldn't be sexist, racist, or competitive. Thanks in advance!
