I think he is pointless because he does nothing for about 3.25 discs.
He joins in right near the end of disc 1 fails at what you needed him to do then helps everyone to remember the past and then that's it!
The only other noticable thing about him is the fact that he is soooo desperate for Selphie.
That's pretty much why...
Oh yeah and he doesn't fit in. A group of elite soldiers and a cowboy...(and a girl and her dog)
You kinda have a point.
He reminds me of Zack Morris from Saved by the Bell...damn gigalo.
