The G Shield -
What does the "G" in the name stand for? Who knows? Maybe you'll find out in the story or you won't, we will all see.
Alright, here is the deal - The story is, as usual, a self insert into the MCU (for some reason I love that fandom). There is the usual ROB scene where he gets perks of some sort. He also gets a primary powerset which is, in his opinion, fairly OP for everyone except the peak of the power ceiling in MCU [Celestials, Skyfathers of Pantheons, Outer Dimension Gods and their avatars, etc.].
For more, just read the prologue.
