The Bird Men special mission. Bird Men can espy enemy planets' minerals, cash and -- most importantly -- friendly code. With Super Spy Deluxe they can even change the planets' friendly code. Note that Super Spy Deluxe is not a genuine mission, it's just a second part of the normal Super Spy mission. Essentially, normal Super Spy happens after movement (i.e. at the planet you move to), and Super Spy Deluxe happens before movement (i.e. in the next turn when you are at the planet).
When the friendly code change succeeds, the victim has a certain chance to counter with an ionic pulse.
