Krang, Chrell, and Aska

As mentioned previously, Ch'rell discovers he can give birth, by finding out he's pregnant. Aska ends up being their sole child, because he decides he's never doing that shit again. And thus, Aska grows up with a lot of attention - packed on with the attention she already gets being the Emperor's grandchild. 

The idea of Krang and Ch'rell as fathers comes as a shock to their enemies (and even some other Utroms), and even greater when they're attentive to her - which is no surprise to their allies, the Lords of Hyperion (one of which Krang is talking to on a communication screen). Aska was even named after a Lord of Hyperion female who helped them during a dire period of political unrest while Ch'rell was pregnant. 

They nicknamed her "Fish" on account of how she looked when she'd be buried in their whiskers. A bit like a fish in an anemone or seaweed.
