I don’t think my headcanon is willing to include ”Invasion From Below” in the timeline.
For one thing, their voices are altered,
For another, the episode was so cringy I don’t think I bothered watching all of it (why the heck did they say so much stuff out-loud?),
And finally, if they can just summon these vast machines of war at a moment’s notice, how is anything smaller than a skyscraper a threat to them going forward?
