One of the most invasive species is the domestic house cat. It has exterminated many species of animals and kills untold billions of animals each year.

It was domesticated in the Near East, so technically from Asia, I guess?

You mentioned Burmese pythons, which are invasive in the Everglades and Florida in general. Do you know about the Australian plant species Melaleuca quinquenervia? From https://en.wikipedia.org/wiki/Melaleuca_quinquenervia :
