Let me see how much I can remember without Wikipedia. Rey beat Ultimo on the first Thunder, I think. Didn't Finlay beat Booker for the TV title on Thunder? There was a Hart-Luger US title change on Thunder but I don't remember if it was Luger winning or Bret winning it back. I think it was the latter. Benoit and Saturn beat the Triad for the tag titles on a Thunder and then lost them three days later on a PPV.
During and between the Russo runs there were a lot more.
- Bret and Goldberg beat Creative Control for the tag titles.
- The Mamalukes beat David Flair and Crowbar for the tag titles
- DAVID ARQUETTE won the world title
- Nash beat Jarrett (and Steiner in a three-way) for the title in May 2000 and then gave the title to Flair on Nitro so he didn't have to job
- I think Chavo beat Mike Sanders for the cruiserweight title in late 2000
I'm sure there are a bunch more, especially once they introduced the Hardcore title, but the Russo era runs together.
Now I'm going to Wikipedia to fill in the blanks
I was right about Bret, he did win it back on Thunder. But I was wrong about Finlay, that was Nitro.
Stasiak and Palumbo won the titles on a Thunder from Kronik, which I kinda remember. And then Palumbo and O'Haire lost the titles in Australia to the Misfits in Action but won them back the same night. I don't remember that at all.
Juventud beat Ultimo on the first Thunder, and Rey beat Juvy on the second episode.
I was right about Chavo. He also defeated Daffney for the title six months earlier.
Terry Funk beat Shane Douglas for the Hardcore title and Crowbar beat Reno.
I think that covers it.
