When Big Meks go to war they do it in style; festooned in massive mechanised contraptions of their own design and brimming with kustom dakka.
The Big Mek is armed with a kustom mega-blasta and power klaw (which also functions as Mek’s tools for battlefield repairs). Your big Mek can also be equipped with a back mounted kustom forcefield or a tellyport blasta and comes with a Grot Oiler; a diminutive assistant that is mostly employed putting out fires or crawling into functioning machinery.
This multi-part plastic kit makes three Meganobz, one of which can be assembled as the Big Mek in Mega Armour.
