This episode of Invader Zim introduces yet another unique character and antagonist to the series, Tak. Only her plan isn't just to prove herself as an invader to the Almighty Tallest, but to prove to Zim she'll always be the better invader between the two. And thus began the battle between two invaders to see which one will be the victorious invader of planet earth.
Tak was such an interesting character to watch all throughout this episode because she was both a great antagonist to Zim and the others, and also felt similar to Zim in some ways including personality (Also brilliant voice work by Olivia D'Abo while we're at it). Not only that, she actually had a real good plan, unlike Zim and his numerous minor and failed attempts. She thinks about every detail, she blends in very well among humans, and she knows how to take down an enemy when she sees one.
The dynamic duo of Dib and Zim also played as a very interesting element in this episode as well because very rarely in the series did we ever see Dib and Zim, let alone Gaz and Gir along side them work together against a common enemy. When you see this group work together, it's almost as if they can be just as good as destroying the world if they are saving it. But sadly in the end, when everyone has a separate goal, it can't stay together.
Overall, a very entertaining and fun episode to watch. I would definitely recommend this episode to anyone who is interested in seeing more about the world of Invader Zim. And who knows, maybe this might be a good episode to learn more about Tak if she ever does make another appearance in the new special coming out sometime soon.
