He fought Hawk Moth too, and killed him
Yeah he killed him unintentionally
He even said so himself
It does because the first thing he did after Ladybug made it clear she won't give her miraculous, is trying to nuke the galaxy. And all of his attacks missed Ladybug on purpose, because he wanted her to give up and surrender her miraculous to him
Okay
So how would that play out against Ultron then?
What he sees thid robot dude and his first course of action is to end everthing including himself?
He had a reason to end world against ladybug
Whats the reason he is gonna that against this robot he has never met before?
He fought Hawk Moth as well, and the first thing he did is to use the AoE attack to kill him and Ladybug since he couldn't choose
Again
He said he DID NOT MEAN TO
The LITERALLY says this to ladybug
And that was a one time occurance under specific amounts of emotional pressure
He's never used AoE cataclysm outside of being under pressure and EoW cataclysm is something he wont resort to because the reason isnt there
And in either AoE case
Ultron can use Galactic AoE to counter or Telekinesis Cat before cataclysm takes place
Um no. We know that the only reason he didn't killed Ladybug is because he wanted her miraculous. Remove that, and nothing stops Cat Blanc for going for the kill here with AoE attacks
So your saying if Ladybug appeared and didnt have miraculous he would choose to nuke everything immediately?
Thats something that never happened in canon so you cant really say that
And also the reason why was gonna nuke everything was because he believed Ladybug didnt love him anymore
He literally says so himself
His hand would disintigrate by the Cataclysm if he would attempt that
How would that happen when Ultron opening move is TK?
Cataclysm would not even occur because First move TK stops him
He can make it bigger. He only used small attacks to not kill Ladybug and destroy the miraculous. All of the usual stuff you said rely on Cat fighting Ladybug and only her. Once he given up of the idea to get her miraculous, he tried to destroy her with an AoE attack
Wrong
He gave up resorted because he believed she didnt love him and he literally says this
