Actually I was thinking about Nero's combat aptitude and tactics.....and I went to the novel of DMC4 to find some interesting stuff....
Nero is alot smarter than he looks.....and he will not start with DT at all even if he reads power lvl of Danny....he will play like a cool customer.....lure and goad Danny into CQC by talking smack and taunting. This is his standard tactic in fights because most enemies and bosses have true flight and they like to spam ranged attacks of all kinds. So Nero's tactic has always been luring or forcefully grappling his enemies iftaunting fails.
And when Danny arrives closer he will closer he will trick Danny and get a drop on him by unleashing all of his DT and all of his attacks at the same time catch him off guard and in the chaos Danny gets hit.
I will provide some excerpts from Novels to back this aspect of Nero's creativity...
1) "When the pope finished, I shot the bullet full of magic.
Although he immediately opened the wall, the bullet shot
at his feet. This trick has been used to deal with Dante,
but I can't think of a better way. The pope looked at his
feet.
Three, two, one...
I meditated in my mind and slowly shortened the distance.
When the countdown reached zero, I waved my sword and
jumped up. At the same time, the bullets at the foot of the
Pope exploded because of the magic, and seized the pope’s
horror. Let the strength of the whole body cut the sword"
As you can read Nero shoots Blue Rose into the ground...it shoots 2 bullets a time, first bullet penetrates and 2nd explodes in a fiery demonic burst after a delay like a mine.
This is impressive because this has been to catch Dante of all people off guard who has Instinctive Reactions and has dealt with such trap attacks throughout his life.
2)"
He said so, I am completely ignorant. I focus my magic on
my right hand:
The right hand held the gun and fired the magic bullet.
Dante prepared to block the attack and set up the figure.
However, my purpose was not Dante, but the pillar next
to him. The bullet hit the stone pillar, but it was not
finished yet, nothing happened at the moment.
"...you missed it."
Dante said with a smile, slowly turned to look at the
pillar. I laughed:
"You'd better stay away."
I did not care to remind him that with the character of the
guy, even if he let him go, he would not be obedient, as I
expected, but Dante looked at the pillars motionlessly, and
then the bullets embedded in the pillars happened. A
violent explosion.
"Oh oh...!?"
3)
"I will save you right away... trust me."
I saw that Kyrie nodded lightly, and then
deliberately annoyed the Pope to lift the sword.
"Let's put down the sword! Otherwise -"
I threw the sword to the Pope, and I didn’t use
much strength, just like I really wanted to give
him. The Pope didn’t think I would have such
actions, and confusedly focused on the air. I don’t
pay attention to me and Kyrie. At this point, I
immediately stretched out my right hand. This is
my other weapon, the hand of the devil. The white
wrist sticking out from my right hand went
straight to the pope. Did not give him the
opportunity to start with Kyrie, the devil's
hand slammed the pope's body on the wall behind
him. This impact force caused the pope's body to
shrink, and I immediately jumped into the air,
sharply Shortened the distance between the Pope and the knives thrown into the air. Let this
scumbag in his own trap can really make people
happy, I smiled, shouting falling from the sky:
"Jackpot!"
Nero dealing with a hostage situation.
4) Theres also instances of him storing up his DT and only unleashing his Yamato and DT at the last moment to catch his opponent off guard.
Tl,dr;
Nero has dealt with alot of unconventional attacks from a lot of whacky demons....AoE, Ranged, almost every demon has a attack that comes out of the ground to surprise Nero.....dodging them is second nature to him.
So I think with this new info on Nero's skill it increases his chances of winning.
