alex mercer
(top speed) 180mph (can run up walls and jump over 10 story buildings)(does not get tired)
(powers) superhuman strength(can throw shit across new york)(can punch through two foot thick steel door). ShapeShifting( can take on a person's shape down to the exact detail, when he eats someone he gains all their memories, can turn himself into a weapon example giant blade or thick armour capable of deflecting bullets except large explosions[nuke]). Healing factor ( can heal any wound as long as he eats something[person,zombie,animal, anything living] as well as can heal some health without the need of nourishment[can eat/absorb living thing in seconds]). Super human senses ( can hear and see beyond great distances as well as can see thermal and infected signatures)
iv'e played both games many times over and i gota say it's almost impossibe to kill alex as delson if ya don't have a nuke(i'm excluding prtotype 2 powers)
the only way delson could ever defeat alex if A. he had some masssive back up but even then mercer could absorb powers[cus he can take on the form of what he consumes down to the exact detail] but delson could not absorb mercers powers because hes not human nor is he a conduit. alex survived a fucking nuke when i shot d.u.p with neon it took a good couple shots to even weeken them to the point of going poof into thin air. also the neon gernade can't even captur alex A. because hes way too fucking fast B.good luck shooting through his fucking armour. ok so if ya can with the neon ultimate, hes hoving in the air with his armour still trying to kill delson with the whipfist(delson stays still while shooting his neon at the dudes in the neon bubble, so bam delsons dead and the lasers cant even kill alex with his armour. so neon power out the window
whats next ooh video power well ya still fucked do I need to explain why... no ya i's obvious delsons still fucked
that leaves us with fire and concrete well fires fucking useless A. becasue the dash dose not go that far and B. fire can't get through his armour.
so concrete... this will do damage not much damage but damage none the less mostly because its a solid object delsons fireing(thing that hurts alex the most "blunt damage")however even then it's just small chunks of rock (mercer can deflect minigun fire)
sure the saws of concrete you say i say he can just catch that shit and throw it back way harder(can throw a bus across new york).
so in all delsons fucked unles alex is a pile a mush after a nuke in which ya can throw everything ya got at that pile of mush to completly kill him down to the molecular level
