Wow, this is a cool match up.
First thing, Digi correct me if I'm wrong but I think you shorted my strength in the description above. Dreadstar's sword is amping Benedict's already superhuman strength, not Vanth's normal human body. Benedict 's normal strength is enough to chop down trees with one slash from a broadsword and throw another warrior 20 yards with one arm. Benedict's strength times ten will be significantly more than Dreadstar's tonnish range.
Second, The frozen north is actually not a terrain advantage for TBK Ben Dreadcrawler posseses Dreadstar's experience of growing up orphanned in the frozen wastes his frozen homefowld of Byfrexia. He spent his adolescence and young-adult life hunting decimating the population of enourmous Snow Bears of the variety that ate his parents before his very eyes. Years later he fought a guerilla war in the exact same environment. TBK's senses are superior, but Benedict's are still slightly superhuman.
Ben Dreadcrawler's openning move is four quick teleports in rapid sucession in random directions, then laying a trail of footprints through the snow heading for a good ambush spot. He then boobytrapt that ambush spot with a hi-ex grenade. He'll then teleport to a position where he could snipe the boobytrap spot and place his rifle so that the barrel is just slightly visable out from cover. Then he'll close his suit's environmental seals (he's doing this to hide his body heat and fog from his breath, but it'll conceal his scent well too). A super-strong nightcrawler leap-flip or two and he'll be waiting in an upwind + up a tree double ambush spot, waiting for HBK to "see through his trap." When he atacks the sulfur smelling bush that has my rifle by it. I'll tag him with my Radium Laser.
