The Godlike Mechanical Engineer in Marvel

With the Super God Mechanic System in hand, I transmigrated into the Marvel Universe as Dr. Zola’s assistant. I have a Mechanical Force analysis skill that lets me learn all of Marvel’s cutting-edge technology. The Winter Soldier’s arm? I’ll build you a better one. Iron Man’s armor? I made it ten years ago. Doctor Octopus’s tentacles? I’ll provide the key technological breakthrough. The Hulk’s mutation? Sorry, I was there at the time and got exposed to radiation too. And that purple, bald guy: will he manage to collect the Infinity Stones? ...But I have just one humble ultimate dream: to go home...
