My last post was lost (sigh). So instead of trying to make one post a week, I'll make shorter ones.
Usagi Yojimbo 107 is putting together a number of characters and earlier threads. We also see a one-page bonus: Usagi vs Groo with a clear winner.
In Foolkiller 2, we learn the origin of the main character. We also get to see issues of Man-Thing and Omega the Unknown, the two series in which Steve Gerber introduced the Foolkiller.
