Morphology

invasion = invade (transparent) = invade + sion

Derived from the verb 'invade' by standard noun formation; the sense 'entering in large numbers' is a direct extension of 'invade'.

Etymology

Invasion comes from the Latin parts in- 'into' and vadere 'to go', which is like the English word 'go'. It gives the image of many things 'going into' a place at once, so we also use it for a sudden mass entry of ants, fans, or photographers.
