...Okay, this might be a bit of a stretch, but bear with me here. After rereading a good chunk of Animorphs lately around the same time as I was playing the Xbox 360 remake of Perfect Dark, one of my favorite games ever, me and my boyfriend started noticing all of these little similarities...
1. There's a Ketran named Farsight in The Ellimist Chronicles.
2. The whole plot around the David trilogy with the Yeerks trying to kidnap the president off Marine One, and Visser Three morphing into a "clone" of him.
3. Aliens infiltrating the NSA
4. Both have version of the "Greys" - Maians and Skrit Na
5. There's a navy admiral named Carrington in book #46
Perhaps I'm just a nerd (well, that's a given) but I couldn't help but notice these things. The time periods add up too - Perfect Dark came out in 2000. Makes me wonder whether KAA's kid was playing it at the time, and she picked up a few ideas from the game. There are tons of other popular culture references in the series (one of the things I love about it, it'll always be notable as a '90s series), so it wouldn't be too surprising.
