WAIT!

More specifically, when you reach the edge of the continent and the game asks if you want to wait or jump, you select wait, and wait until the timer ticks all the way down to less than 10 seconds. The timer will vanish, Shadow will come, and you will be able to recruit him in the WoR like everyone else.

Q. We all know Gogo is a throw-back character that appeared in FFV. There is one other FFV character that makes an appearance in FFVI as well. Who is it? (Note: this is for all versions of the game, not just the Advance version, so I'm not talking about a certain multi-armed weapons collector)
