i am searching for all the issues of the blood and thunder saga of thor. i have part one and the final part but i want the one where thor fights surfer but i don't know what issue of infinity watchman it's in so if some one knows reply to this and if u could tell me the other issues of it

The issues are:

Part 1: Thor #468
Part 2: Silver Surfer #86
Part 3: The Warlock Chronicles #6
Part 4: Warlock & the Infinity Watch #23
Part 5: Thor #469
Part 6: Silver Surfer #87
Part 7: The Warlock Chronicles #7
Part 8: Warlock & the Infinity Watch #24
Part 9: Thor #470
Part 10: Silver Surfer #88
Part 11: The Warlock Chronicles #8
Part 12: Warlock & the Infinity Watch #25
Part 13: Thor #471

I believe the issue where Silver Surfer and Thor fight is in Silver Surfer #86. If my memory is correct, Thor wins.
I also enjoyed Silver Surfer #88, Thanos vs Thor... Thor's power is suped-up by being in posession of Drax's Power Gem. It is quite the fight.
Warlock & the Infinity Watch #25 has an awesome Thanos vs Odin fight, in which Odin takes out Silver Surfer in one blast (after Thanos gets hit with the same and still stands.)
Blood and Thunder is one of my favorite Cosmic Crossover storylines. I would definitely recommend it.

Hope this helps.

thank u for your help indeed this does save me alot of time on ebay
