could there be one where he actually revealed archer's identity?

OP archer? Not scary, Try Hapsiel as a Berserker. :-)

Ah, but Superman would have had a critical weakness in a Holy Grail War. He has absolutely NO magic resistance.

This conjures visions for other off-the-wall summons: consider Harry Flashman, who could fill any role save Caster, but would be desperately trying to leave the city after bedding all the women; or perhaps James Bigglesworth as Servant Rider (would his noble phantasm be a Sopwith Camel, or a Supermarine Spitfire?)

Nice

LOL poor homura and also interesting idea

Homura need a drink and some... no, a lot of love!

The only way this could've been even more hilarious is if Shirou told them who Archer actually was. Homura would've just given up on trying to make sense of anything Shirou-related after that.

while I'd admit this was amusing, and I did enjoy reading it, you didn't separate it from in flight. all this is just chapter 31 with a couple more paragraphs. I expected you to tell them about archer.

Funny than I thought, really not what I expect.

In all honesty, that would mean that Ezio would have been Assassin as well...and Pit from Kid Icarus would have been at least FIVE different classes.

But no...it was EMIYA.

poor Homura, your desire will not come true, he / she is dealing with Shirou after all.

...we need more of these...

Oh,and I have a major fan fiction challenge for you.

If you have seen In Flight...And The Emerald Blade spinoff...here is a new one...

Shirou and gang don't survive past the Jinki activating...instead a different result comes and the gang(humans and sekirei) arrive in the ...4th...5th...Holy grail war!(u decide...I think fighting alongside Alexander would be interesting though.)

This is amusing as can be, in part because I've read a one shot that addressed Superman as a Servant, Chapter 19 of 'Infinite Paths' by Lord Mist, if you're interested.
Corvus no Genmu's 'From Across the Throne of Heroes' is another with a wide variety of Servant one shots, everything from Link, to Optimus Prime, to the Stitch, very good read as well.
