The Magu Magu no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into magma at will, turning the user into a Magma Human (マグマ人間 Maguma Ningen?). "Magu" is from "maguma", which is the Japanese pronunciation of the word "magma".
Q - Dai Funka
Dai Funka is a attack where the user charges up a fist then hurls it at the enemy. This does base 50 - 70 damage.
E - Inugami Guren
Inugami is a attack where the user fires a demon dog-shaped blast from their hand. It's the largest of the attacks but is the slowest. It does 60 - 80 base damage.
R - MeigoMeigo is an attack where the user launches an open hand to their opponent to knock them back. This does base 30 - 40 damage.
Magu Magu's Logia Reflex does 10 damage every time someone touches one of the player's limbs.
This fruit can overpower any devil fruit.*
The Magu Magu no mi has no weaknesses.*
*This is only described as such because the anime nor the manga appear to show that the Magu-Magu shows a weakness to anything except standard devil fruit weaknesses.
