Batman 1M is NOT a 'street level' hero. The dude runs an entire penal planet.
Furthermore the dude is, as stated in JLA:1M, 'one half of the system's finest duo.' The other half being Superman 1M, a being that is just insanely powerful. Thus means Batman 1M must have accomplished stuff that sets him as a rather top echelon member of the future JLA.
Add to this that the dude has 'unequaled physical prowess' (I'd pay to see a fight between him and the Justice Legion's Karate Kid since both know intergalactic martial arts), as well as having an IQ of 1045.
Deathstroke may be a genius who can 'use 90% of his brain' (anyone who knows anything about cranial function should find the 90% thing ridiculously funny, but I digress) ....anyways, Deathstroke may be a genius, but the future Batdude is just beyond him.
Geez, the guy even knows telepathic martial arts.
Now, Shi'ar technology should definitely help the current guys quite a bit, although to be honest with you Batman 1M should win.
Even when the other dudes have the Shi'ar tech.
A good analogy would be like giving three 8th graders access to the finest combat weapons. Thus the 8th graders (in this case standing for Deathstroke, Midnighter and Deadpool) have HnK XM-8s, FN SCAR prototype rifles with 40mm grenade launchers with 'smart-grenades,' infra-red scopes up the wazoo, sensory enhacement equipment...etc etc etc. Basically everything Darpa is developing for the next generation American soldier.
Thus they are quite well equipped.
And then you have them go into battle against a single Navy SEAL with his several year old CAR-15, several MK2 frag grenades, and a bunch of claymores from the late Viet Nam era.
It really will not matter much if the three 8th graders have access to next-gen tech ....they will still be killed by the Navy SEAL.
Same thing here .....Batman 1M still wins. And with ease.
As for Deadpool ....he may have a healing factor, but I wonder how he would function without his soul).
