Well with no batman in gotham, he can blow up entire city getting rid of all the scum and getting lots of murder points. Even kill Lex Luthor while he is at it. Even if he is a good guy.
Correct There isn't any powerful kryptonians on Arrowverse, but I was thinking the The Flashpoint movie verse Supergirl ( Sasha Calle) Unless you have Barry Allen Super Speed dimension hopping powers ,Oliver Queen ( David) has no way of getting to Earth 38' Supergirl ( Melissa Benoit)yet and much-needed less there being a actual kryptonian on Arrowverse Alternative hasn't yet been explored by Oliver Queen ( David) in his new make shift plans for Starling City.
Well this certainly changes things for Oliver Queen ( David ) oj going forward in the alternative Arrowverse universe. especially since their isn't no big 3 for the future Justice league ( Wonder Woman, Flash,Superman). which means there's a Supergirl ( Sasha Calle)( Flash movie version )out there . Guess we'll see how Oliver Queen adjusting to new life in Starling City and no Justice league to back him up in the future, but I'm sure Oliver Queen ( David) is going to build a very different Justice league ?My best speculation guesses?Continue on Cheers!
