I've seen so many questions similar to this and most of the answers are highly opinionated or confusing. So thought of sharing my logic and opinions to all by explaining nature of Sri Vishnu and who wins the battle between lord Rama and others.
In a common perspective, Yes.
But in every other higher/celestial perspective “NO”.
Scientifically, if every being in earth gets energy from the Sun and the Sun and all another planet (Dev/Devi’s) gets energy from Sri Vishnu (Paramatman).
But first, you need to understand the nature of Rama (Vishnu). We all know Rama is an avatar of Vishnu the one and infinite. Inspired from computers, think of Rama is an upgraded version of program shortcuts we use, it can contain different names, colors, images or styles but its source is the one where is links. He can scale and hold the power from the source to balance the creation, do whatever it takes to eliminate the corrupt or preserving the correct.
He is Shiva, Brahma, Hanuman, Lav-Kush and he is everything you’ll ever think of. He is who constantly writes and contains the all imaginary universes, Mayas, energies etc.
We all know the entity called “Paramatman” which Sri Krishna explained to Arjun in Mahabharata is in every living being. “Aatman” is a part of “Paramaatman”. In every cycle of creation it moves, it wears bodies of different living beings which metaphorically described in holy Gita as similar to our cloth changing.
Both birth and death is a part of creation, when you are born you take a seat and it vacant when “Aatman” leaves and then some other “Aatman” fills up your space.
If you think this way, that you are a tiny form of composed energy (which we are) in an infinite sea of energy. Everything changes, so drastically that it leaves a blank in one’s mind. We as energy just moving from one to other, constantly influenced by other energies. Birth and death is just another chemical reaction in an infinite universe tube.
And this theory summarizes the source of all energy who is none other than Paramatman Sri Vishnu.
To teach us at our level of understanding. He holds the power and energy to conquer anything. And he does it every avatar. He conquers himself by giving priority to everything other than his name. He chooses to love and devotion before fear. That's why he is greatest.
Also, he is the source of all energy, to which energy he needs to prove his strength? Comparing any fight between "Paramatman" and any other being is like, fighting with your one arm with another and judging who won.
These are my thoughts/opinions, just like others. But why I’m so confident about this answer is I’ve given celestial knowledge priority. It's common knowledge, that celestial beings have so much more IQ and the standards of processing such judgments than a mere human.
