Escaping through the window is usually a good idea, but not even Megatak will be able to outrun Thor. Thor can fly at incredible speeds and he can easily defeat Megatak in a close combat battle. Megatak is decently powerful and he can create energy constructs out of binary codes from the universe, but his hand to hand skills aren’t at Thor’s level. Thor also has the superior strength and speed factors at his disposal. Thor wins.
