The first time that Zack saw Angeal was long before he entered the SOLDIER program. Gongaga was having problems with monsters and Angeal was the one sent to exterminate them. From the first time he saw the man with the Buster Sword Zack knew that he would one day be a hero like Angeal.
The first time Angeal saw Zack was through a two-way mirror. The firsts were required to check up on the training of cadets once a month to see if any were naturally talented. Most of this year's class were average but all three firsts agreed that there was one cadet that showed great promise. The three watched the black haired cadet go through the drills with ease until the unexpected happened. When all the drills had been completed the teen quickly spun the sword behind his head and then lost his grip. The sword had enough momentum that it went flying across the room, smashed through the two-way mirror, and landed point down between Genesis's feet. In the few seconds were everyone stared in shock Angeal grabbed Genesis and pulled him from the room.
"That boy," Genesis growled, "will never become a SOLDIER."
