Of all the season two mobile suits in the Iron Blooded Orphans series, the Helmwige Reincar made the biggest impact. Granted, although it was nothing more than a modified, beefed up Grimgerde that fulfilled the role of a glorified sword holder for the Barbatos Lupus, the Helmwige is still one of the best, refreshing designs that came out from the series.
Reusing the Grimgerde's frame, the Helmwige adds on more armor and thrusters to create a bovine-looking bruiser. Despite its size, the Helmwige is able to pull off most dynamic poses, although the huge buster sword is ironically a chore to pose with.
A chameleon black-gold colour scheme was chosen for the Helmwige as it needs a little help to camouflage itself given its massive bulk. As the series is coming to an end, I hope the Helmwige Reincar doesn't meet an untimely end, judging from how the plot is going.
