Danzo may or may not be stronger since he doesnt have Hashi cells. Itachi also hasnt shown signs of illness. In fact this time period is very close to when he solo'd Orochimaru.
So basically you proved that Danzo underestimates his opponents severely and is an idiot. Cool.
Prove what? Itachi looks at him, shoots nigh instantaneous fire, Danzo dies or wastes inzanami. Novice or not Amaterasu isn't hard to use. Novice Sasuke did fine with it.
Sasuke was a novice with his susanoo and still killed danzo.
Tsukiyomi would be the same as Amaterasu.
Itachi would solo Danzo.
Danzo was scared of Tsukiyomi.
The Danzo we saw fighting Sasuke was holding back, and would had also suffered weakness from age despite gaining new powers. Itachi himself hadn't shown signs of mastery of any MS jutsu except Tsukiyomi. Orochimaru was also dying and not trying to kill Itachi.
That is a lie. Danzo was being prudent, using only as much power as he needed so he could run a gauntlet.
Amaterasu is a fireball, it isn't instantaneous. If it were, MS Sasuke needing EMS to fight Naruto is pointless since MS Sasuke could one-shot current Naruto... that is
not the case.
A Danzo that was older and slower, and lacked concern. He used Izanagi for defense, just as Itachi uses Susanoo for defense.
Only if Danzo stared directly into Itachi's eyes, which he will know not to do since he's an Uchiha.
In a one-on-one fight, one would hope Itachi could prevail by himself.
When did Danzo show fear of Tsukiyomi?
