Just cause I could see the two of them teaming up to pester Angel.

ahhh i can imagine some very funny scenes in S5 of angel :)

Spike and Cordy are so alike, they could be awesome friends, but overall, I think he and Oz would complement each other better.

Who can't get along with Oz?

he likes anya, and she has a simular charachter like cordelia. And I think he would get irritated by Oz his silence, like I do.

i think oz and spike are two very strong characters and would not work well together. kind of like spike and angel couldnt help clashing because they were both so stubborn and "hero"ish
cordelia and spike wouldnt exactly get along either, but it would be pretty funny to watch them not get along.

Cordelia would annoy the crap out of him lol. Oz would be quietly understanding, what he does best!

Definitely. Cordy would annoy him like Anya does xD

Although I would love to see Oz and Spike hang out, I gotta say Cordy because they have the same sense of hummor. :)

I just see him and Cordelia crashing all the time.

From the little bit they had on Angel.

He seems to get on better with women.

I think Spike would get along good with both of them, but Cordelia can be very annoying, at least the one before Atvs. Oz is really quiet, so the two of them would not talk very much, but get along very well. And who don't like Oz?
