Fellow Seibertron D-Maximus Primal has sent us some images of the new Ectotron figure with comparisons to the old figure and other crossover figures. He also described the main differences for us and gave a quick review:
You have a brand new and very stylish head sculpt, complete with a faceplate and some nice goggles. It's really nice, better than the original.
There is also retooling done to the legs. The ladder switched sides, and there are new molded bits to accommodate the switch while removing the ladder mounts on the original side.
The deco is inspired by the upcoming Ghostbusters Afterlife film, which was originally coming out last summer but was pushed a year. It's highly anticipated. The new Ectotron features a dirtier white, along the lines of the Star Wars Black Series Remnant Stormtrooper colors, as well as decent rust paint, cracked logos, and even a new logo and rear license plate deco.
It comes with an unpainted Slimer like the original, but also includes a new blue ghost from the upcoming movie.
Overall, it's a very nice new take on Eck. I would say the head outshines the original. And while the rust paint apps could use work, it does have a nice worm feel to it.
I'd recommend it to anyone with an interest in Ghostbusters, and even someone who has the original Ectotron. It's a good mold, and I really enjoy both takes on Eck that we've gotten.
