So this is a question i had in my mind for a while. What would happen if Erica and Melvin fought? Sure, Melvin can create inventions modern science can't even reach. But Erica is more "clever", as shown since she figured out to stop the Messica Gorgon Mess and outsmarted Melvin himself by actually pressing the button in the season 2 two-part finale. So i'm going to compare aspects of them to see who's stronger

-Strength-

Erica wins this by a LANDSLIDE! Melvin is shown to be very weak and can't even sharp a pencil. Meanwhile with Erica, she has top dance lessons, is great at gymnastics, and has great flexibility. But Melvin could cheat by using an invention like the pumpinator 2000 and the Nanobots. But Erica still wins.

Erica: 1

Melvin: 0

-Intelligence-

Even though i complimented about Erica being clever in the beginning, i think Melvin wins this. Sure, Erica's def more clever, but there's a difference between cleverness and intelligence. Erica is pretty clever, but Melvin could make a time machine just by Peanut butter. PEANUT BUTTER. So Melvin wins

Erica: 1

Melvin: 1

-Speed-

I looked at S2E13 and there was a shot where George, Harold, Melvin and Melvinborg are running. And as shown, Melvin and Melvinborg are slower then George and Harold. Here's the shot.

From S2E13

Erica in the other hand is much, much athletic ( has top dance lessons, is great at gymnastics, and has great flexibility ) which could possibly mean she has better speed then Melvin. And that means...

ERICA WINS!

Erica: 2

Melvin: 1

I am planning to do George and Harold next, what do you think of this?
