The entirety of Alect Squadron. There's a reason it's one of the few missions with a full mission transcript.
Falco One: Check your radar! Something's coming from far off! Enemy reinforcements! Look out!
Falco Two: Damn! He's got the sun to his back, I can't see!
Falco One: Don't panic! We've got the Southern Cross!
Alect 1: The battle's begun. So, which one's Nemesis?
Alect 2: I've heard just about enough of your tall tales for one lifetime. It's time to see if you measure up!
Alect 1: All Leasath fighters! Leave this one to me!
Crux: They've come! The Alect Squadron's here! Don't let them near Archelon Fortress! Destroy them all!
