The best way I would describe it is overemphasizing that it’s foreign, and usually part of some sinister plot. There is a large amount of overlap between antisemitic stereotypes and anti-Asian sentiment (particularly anti-Chinese) sentiment, for example.

Sometimes when anime or pokemon was spoofed in the aughts, the animators would get kind of…weird about it. Even some parents and school faculty members would see it as a bad influence, and anime had a moral panic against it. Hell, Pokemon risked having the iconic pokemon redesigned just for the US.
