One of my favorite background lore pieces from Metroid is how the Space Pirates are basically extremely stupid insectoids who more often than not do more damage to themselves with their own bioweapons than the enemies they're intended for.
I still chuckle at the fact that the Pirates killed almost an entire platoon of their own super soldiers by trying to figure out how the fuck Samus' morphball works before eventually giving up and calling it physically impossible and that Samus must be using some kind of space wizard magic bullshit.
