Looking for xbox buddies for my 12yr Son

My lad is asd and is desperately trying to find his kindred to play online. He has found navigating online friendship a real challenge, much like in the real world. So I'm hoping to find some fireteamers for him here.  

He plays a variety games including the staples minecaft, roblox, fortnight etc he loves Destiny particularly. He is always open to trying new games so some recommendations would be appreciated.

Ille most kids he plays on xbox most nights
