(Not mindless power fantasy, and he isn’t invincible from the start. He only gradually becomes invincible after Chapter 20.)
After transmigrating into Marvel, the good news is that I’m bound to a System and have merged with Broly’s bloodline.
The bad news is that I can easily lose control, and when I go berserk, I attack my own side too.
So I have to keep my temper in check while stealing kills in the Avengers.
I kick Loki, save Quicksilver, break up fights between Captain America and Iron Man, and even teach Thanos a lesson.
They all know I’m ridiculously powerful, but only I know that I just want to finish my missions and go home to tuck my little sister in.
[This is the story of an office drone forced to become a Saiyan, who in the end just wants to go home and tuck his little sister in.]
Some of the first settings may dissuade a wave of people, but the later ones are pretty good, except that the protagonist doesn't practice and regards bloodline concentration as combat power. I don't know if I will practice in the future. See Chapter 34
Well enough. Come on, author, come on, author!
