What’s the longest Battle Chain?

[Toast]

Here’s what I mean: Let’s say you go to Goku’s page, scroll down, and see he has a win, loss, or incon against some Joe Shmoe. Then you go to Joe’s page and see he has a win or loss or whatnot against someone else, then you go to their page and scroll down and see they have no notable wins, losses, or the like. That would be a chain with three total links/parts. Thusly, I pose the question: What’s the longest chain on the wiki? Without using the same character twice, of course.
