One Piece: Wrong Fruit at the Start, I'm Invincible

What Tremor-Tremor Fruit, what Dark-Dark Fruit, what Nika Fruit, what Rumble-Rumble Fruit-they're all weak. Moke, who had transmigrated, in order to become stronger, tried every means to board Alvida's ship, intending to snatch the Paramecia-type Slip-Slip Fruit from her hands, thereby gaining a foothold in the pirate world. But unexpectedly, he grabbed the wrong Devil Fruit and accidentally ate the Paramecia-type Absorb-Absorb Fruit. It can absorb all substances it touches, then assimilate his body into the same substance. Touching iron, he becomes an iron man. Touching the magma blasted by Akainu, he immediately becomes a magma man, absorbing the damage and counterattacking with multiplied force. He can even elementalize like a Logia ability user. If the Dark-Dark Fruit is the most special existence among Logia, then this Absorb-Absorb Fruit is absolutely the most special existence among Paramecia. Even the Nika Fruit has to step aside.
