Batman vs Thanos with THOTU.
Since everyone including writers seem intent on making Batman superhuman (his capicity for learning all languages, martial arts, electronics, detective work, computers, electronic repairs, 100 foot falls) let him fight Thanos. Of course Batman is given 2 months and a half of preptime, any and all weapons, suits and vehicles he has. He can even have Robin and Nightwings assistance. Now Batman is one of my most favorite superheros but I think he is often given too much credit, I mean God look at his performance in Hush. This is gonna get punky all riled up but what the hell. And I reiterate I love Batman almost as much as punky.
