Green Lantern Power Battery - Green Lantern (Comics)
By DC Direct
I'm not 100% sure, but I think this may have been my first prop replica. It was the first Power Battery replica offered by DC Direct and was a limited edition. It has a Power Ring that makes the battery light up when it's placed in the center of the...uh...lighty area.
Green Lantern has always been one of my very favorite heroes, and was one of the first I discovered as a kid when I started to read comics other than Batman. I have now had this piece for close to 15 years, and it still gives me a little nerdy rush when I see it sitting on the shelf.
This model is long-since discontinued, but they have made a few other versions. It seems that all that is available at the time of this writing, however, is the White Lantern Power Battery.
