Biography
''A venomous Decepticon, Contagion powers himself on the misfortunes of others. Bathing the battlefield in toxic gas he spreads his own brand of dark destruction, stripping enemies down to their gearboxes with searing SMGs. Those big tanks on his back aren’t just for show - damaged Decepticons at close range will find their rust repaired and their batteries boosted. Anyone not in his squad should probably give him a wide berth.''
