What is your favourite Maiden made-up or actual portmanteau?

[Genghis Khan]

All of the following songs are portmanteaus whether actual (e.g. Journeyman) or made up by brilliant Iron Maiden minds (e.g. Wrathchild).  This poll is different from SMX's "One Word -- AWESOME" poll because it does not contain ALL one word songs, e.g. no Paschendale.  This will make voting presumably tougher.

I've narrowed it down to four:
Futureal -- Great quick opener.  I like fast songs that don't let up.  But is it good enough to be the best here.
Tailgunner -- I find this a better opener despite the lyrics most people cringe at.  The drums, the main riff and the bridge and way Bruce spits out the name, gets me into this song.
Powerslave -- I am gaining respect for this song more and more.  The mystery behind it makes me find something more in this song every time I listen to it, but...
Rainmaker -- Recently I am even more into this song.  It has a great solo and passionate singing.  It gets my vote.

Powerslave just nicked it.  I'm a big fan of the album as a whole and that was enough to pip Rainmaker into second

that's an easy one Genghis !!

Powerslave -one of my 7 best Maiden songs anyway -I've voted allready for it in Lovro's poll-

my respect for that song growed enormously when I read about it in IMC

I'm opting for Tailgunner here. It was the first track I heard from No Prayer (prior to its release) and it has always stuck with me. Possibly, one of Maiden's best openers.

The video to it is pretty good as well.
