Scorpio cannot bring in his Key since it is a special object, correct? Or since he begins the game placing it, I am not adding it to my force?

MASTER OF THE ZODIAC: Scorpio begins the game with the Zodiac Key placed on the map by an opponent into a clear square at least five squares from any starting area. Scorpio automatically rolls a 6 when rolling for the Zodiac Key. When Scorpio is KO'ed, remove the Zodiac Key form the game. Scorpio can use Energy Shield/Deflection and Penetrating/Psychic Blast while the Zodiac key is on his character card.

Setup - Infinity Gauntlet dial begins on the green line, but does not have a KO click; the dial may rotate past the starting line. You may not add special objects to your force if Infinity Gauntlet is part of it.

The Key is not a part of your force and as such can be in the game even if you play the Gauntlet.

The same goes for #40 Cap's Shield.

EDIT: Oh, and the important "This object does not count towards your force."-sentence is in his other trait.

Thanks, I did all kinds of searches, but had no luck finding this answer.
