If you don't know the heartbreaker, shame be upon you. 




The Mark 17 has a red and gold color scheme, like most of it's predecessors,  and the usual Iron Man suit. It has a bulkier but fit appearance, because of its thicker multiple-layered titanium platings, and has an oversized chest repulsor RT built within the suit's armored chest area, which is it's most unique and notable feature, and is also where it's special abilities lie.


The suit has four titanium bar-like structures in the chest area, that are interlocked with the suit, which extend all the way to the shoulder plates and down to the back, then back to the chest area, through the sides of the upper abdomen area, which creates an x-like appearance that firmly holds the oversized chest repulsor together, as well as providing more space for the Unibeam's size.

Oh and it also has the same helmet design as the Mark 11, but same with the 11, the specialized helmet is so similar to the original, doing it in minecraft would be impractical and would probably result in making it ugly :P
