So what elecktra doesn't know everything and can't defeat everything.
She can only see alittle into the future, so what.
The most skilled Japanese samarai had the same ability of near futrue precog.
It doesn't mean she can depict everysingle thing that will happen only a few real crucial moments, but just cause you know something doesn't mean you can always stop it.
Besides are you even familiar with quantum physica or the theory of the space/ time curviture.
That if you change something in the past it effects the future in sometimes unseen ways.
This being said, whatever she sees is the future, when she is in the situation leading up to this, she is in the past of that future, meaning whatever she does or tries to change can backfire on her, causing maybe even a more gruling effect to occur in the future.
If you change one thing, something else happens.
That being said, it doens't even matter cause batman has a slight pre cog in heightened senses and total control over mind and body, hwich allows a karata to glance at an opponent and know what he will do befor he does it.
Electra only sees a crucial future moment, but knows not how it occusr til it happens. (so the above theory applies mainly to her).
However, batman doesn't see the future, he just knows what you're finna do, which means he is alraedy steps ahead of you before you even attack.
He breaks electra down as soon as she takes a stance, then they began to fight, in about 30 seconds, she sees the vision again, this time as it unfolds before her, she tries to do something to overt it, and still dies by some other "unseen" means.
This is bacially the theory, it can be changed by certain factors that are involved, but yes it can occur.
Besides, she isn't fighting some ninja or some garbage ass fack bogyguards or even some mediocre black belt assassin, she is fighting the batman.
Batman ****in' man, dude.
He mops the floor with her.
DD, he will be more of a challenge than elecktra.
He still goes down too.
