Not Ultra Magnus, Ultimetal Magnus. Or rather an Ultimetal Magnus of Ultra Magnus.
This is confusing.
Joining his “brother”, we have what is almost certainly an Ultra Magnus themed recolor of UM-01. The colorization seems to be based most heavily on the MP-2 version of Inner Magnus. Art on display above the model also heavily hints at some proper Magnus armor. Given the base figure is already sixteen inches tall, a fully armored Magnus will finally exist for everyone who thought Citizen Stack was simply too small.
Thanks to Cybergundam for the news. You can scope their post out here as well as discuss this new figure with your fellow fans on the Allspark.
