well if thats all he can do is be super strong and super fast thats not gonna do it slade has taken out people that are super strong and super fast and he himself is super strong and super fast, He has cut cyborg who is super strong and made of metal with his sword which is like adimantium he has knocked people like supes with his staff and once ran as fast as kid flash and hit him only for a few seconds but yeah it happend im sure they will say its PIS but thats not true since its happend more then 2 times maybe 4 times.
You seem to find it hard to believe yourself Mider. Vargas took on the entire X-men and had them on the run... Slade will be ripped to pieces, and his costume and weapons will be on display in Vargas' trophy case, without the invulnerabilty that Superman has he would have taken plenty more a** kickings than he has, lets face it Kal-El can't fight if Batman were in his league as far as Super powers are concerned he'd own him. Vargas is a beast when it comes to hand to hand combat, as a matter of fact, I'd say he beats cyborg in under a minute. Slade.. well he might have to work up a sweat, but in the end Vargas will kill him with his own sword.
entire x-men? is that all who cares? Slade has taken the teen titans, has kept up with kid flash for a perioud of time while running, can shoot kid flash when he's moving at super speed, also can do that to superman, has the agility to evade superman for a while, has taken the teen titans like punks, can servive anti tank fire and even being sliced down the middle, his grenades can knock out superboy and super girl and even WW. He has resisted her lasso by switching his brain to pure instinct mode, i mean if you can please give more info i mean ok he beat all the x-men.......how and so what slade has almost done that to and maybe did so whats your point?
Teen Titans < X-Men, especially the X-Treme team. Superboy and Wonder-Girl are extremely overrated. Also, Slade's a jobber. Vargas is far beyond human or mutant. Imagine a mutant with a secondary mutation, and then that mutation mutates. That's Vargas. His combative abilites are par with Captain America, Deadpool, and Black Panther, all who could clock Slade easy in a fist fight.
Slade for the win? Vargas brought down a building with his sword, was able to take direct hits from Rogue while remaining nearly unfazed by her assault... she even touched his skin absorbing his abilities, and he remained conscious, not even Thor or the Hulk could do this... Slade may be like Vargas but it was clear that Vargas is superior to him in every way, If rogue touched Slade for the same amount of time she'd more than knock him out too.
