X-Men 1 and Batman Begins joking about costumes and the irony

it was explained in X1, X2 and Origins. 





Also adamantium is an indestructible weapon..a hard mineral metal. bonded to wolverine and worked on him because he heals. that is explained. as said in origins sabertooth would never have handled it in his body because he does not heal like wolverine does. adamantium is what you call good science fiction. in X2 you can even see it been formed. styrker says you have to keep it mental cool to get the best results. Noting is known about vibranium yet he solves all their problems its basically magic not science   fiction like adamantium..or is it just generic basic writing like most mcu movies
