It seems that Kat hated Coop from the first moment they met. But Kat had just been on the receiving end of a baseball. Not just any baseball. A baseball thrown দ্বারা Millie... I'm pretty sure that আপনি would have hissed at the first thing আপনি saw if আপনি were in his position!

Coop then attacks Kat with a wave of insults, not the best way to make a friend... Millie does the polar opposite; she welcomes Kat with open arms and insists that they keep him.

How would আপনি feel if আপনি just landed in a foreign country অথবা an alien world and the first creature আপনি meet hates আপনি and wants to be rid of আপনি and the সেকেন্ড loves, feeds and wants to look after you?

Then imagine that this evil creature seeks up to আপনি while আপনি are sleeping and steels your only way to talk to,or go home. আপনি would try to get it back! But how? আপনি can't reason with this creature! So আপনি try to take it দ্বারা force. But then your only way to see your family again is destroyed...

Now আপনি are really mad and have made it your goal to cause as much pain and humiliation to this evil creature, to Coop.

Coop has hundreds of insults about Kat’s appearance. But in Fangs for the Memories Coop complements and enjoys playing with Kat. This means that he doesn’t actually have anything against Kat অথবা his appearance. In Strange Kat on a Train Coop also tells Kat that he has to admit that one of his abilities is pretty cool.

It is only because Coop knows that Kat is an agent commanded to threaten Humanity that he despises him so.

Coop’s point of view is clear and obvious. He is a 10/11 বছর old kid who loves destroying aliens in video games, Watching Captain Blasteroid and saving the Earth. Therefore no matter what Kat does he must be stopped.
