Spider-Man: Infinite Sacrifice

Transmigrated into Gwen Stacy’s universe as Peter Parker, our protagonist realizes he’s not the hero of this story—he’s the tragic backstory. Without spider-powers and facing a "death flag" script, Peter is originally panicking. Fortunately, he awakens the Sacrifice System. By sacrificing items related to Marvel characters, he gains points to strengthen himself. The radioactive spider’s remains? Sacrificed! The Iron Man Mark I armor? Sacrificed! Black Widow’s tactical suit, Heart-Shaped Herb, Chitauri wreckage, Asgardian armor... Sacrifice it all! Rewards Received: The Twelve Talismans (Jackie Chan Adventures), Zanpakuto (Bleach), Six Powers (One Piece), the Rinnegan (Naruto), Kamen Rider Drivers... Starting out low-key in the Big Apple, he eventually ascends to "Homelander" levels of dominance. Peter: "I’ll do whatever the hell I want! Hey, you over there, the giant Purple Potato—what are you looking at?" — Description from novelcodex.org
