Medicom will be releasing an Infinity War Iron-Spider in their MAFEX 1/12 line of figures.
Spidey will come with his mechanical legs, and these are executed by a plug in back section. There will also be two head options with varying eye expressions and alternative hand options. Spider-webbing FX pieces are also included. There are also two alternative foot options containing magnets so Iron Spider can be posed on a wall - as long as its a metal surface - this is something MAFEX are doing on their comicbook Spider-Man.
With the comic Spider-Man on pre-order for around $95 in the US (I can't locate any UK pre-orders yet) then this one is going to exceed that $100 mark easily with the added parts.
