Seriously though, why even focus on her? She builds a locator in 5 years that that no one else has.
Modoc worshipped Kang but then turned against on him because of Cassie, lol. Kang was able to build an advanced empire, they didn't exactly show how, wasted scenes. His tech is so advanced but can't make the 'primitive' tech required to shrink the core.
He is able to freeze people but doesn't near the end. The ants for some reason lived there for 1 thousand years and became really smart but the others didn't. Kang conveniently gets erased at the end.
Post credits, all those kangs cheering like fan girls, they don't look like serious threats at all. What was even the point of bill Murray? No flashbacks, nothing
