Could be either of these guys.
I add this SPIKE purely as a matter of reference. 
Which I think is the only Spike to be sued by another Spike.
Spike Spiegel of Cowboy Bebop, for those who don’t know. He’s the winner, with Spike the vampire in second.
My first thought was the Spike mentioned in post #6.
Then a couple of other spikes.
Of course the first Bach I usually think of is PDQ, too.
Bones!
Oh, wait.
Ying-tong-ying-tong-ying-tong-ying-tong-ying-tong-iddle-i-po
that Spike.
My money is in for Spike.
That’s my pick, even if the third Spike is near-immortal or whatever. I’d like to see Spike #1 direct a movie featuring Mr. Spiegel.
Spike the dog dominates all.
“One Spike to rule them all, One Spike to find them, One Spike to bring them all, And in the darkness bind them.”
Now that we have our nominees, which one is the Ultimate Spike?
I, for one, welcome our new Spike overlords.
Still gotta go with #3.
He shoots the others. Then makes a witty comment.
That’s my Spike, also.
Beat me to it.
