I thought the only thing you cared about was power levels?
No. I have never stated that. Power is just a crucial part! I am big on intelligence though! In fact I enjoy calculus and studying relativity as leisurely activities!
Plankton in the spongebob movie proved to be one of the best villains in my opinion despite being weak in terms of strength. Why is this you ask?
He had the brains and strategy to successfully steal the krabby patty formula, control King Neptune and even take over Bikini Bottom!
It is not just about power to me! It is mainly about efficiency, success and epic entertainment!
I advocate for power so much because massive scale battles like this fulfilled that 3rd requirement that I just listed. I love the first 2 as well.
Have you ever wondered why I always am harsh on Orochimaru? It is because he never provided any of those qualities.
