I Am a Powerhouse in the Marvel Universe

After transmigrating into Marvel, Russell awakens an Attribute Panel that lets him grow without limit by absorbing energy.

Talent 1, Energy Absorption: Absorb any kind of energy and convert it into Lifespan (attribute points).

Talent 2, Attribute Transfer: Convert Lifespan into Constitution, Perception, or Spirit.

Russell thought his destiny was to crush everything with overwhelming stats and become a one-punch hero. Then he realized something was off about Talent 1, Energy Absorption.

Light, electricity, heat, kinetic energy... and all kinds of magical energy.

Under the Ancient One's guidance, Russell starts wreaking havoc among the many dimensional demons.

Russell: “Mephisto, I forgot to collect interest on your compensation last time. Let's settle up.”

Russell: “Beast? Just a primitive demon. I'll refine you in an instant.”

Russell: “Dormammu, I'm here to negotiate.”

And there's E=mc². Mass can be converted into energy too... The multiverse, you look delicious.

Also known as Russell Isn't a Stat Monster, This Sorcerer Supreme Isn't Much of a Sorcerer, and Me and My Sorcerer Supreme Squad
