It's feeding time
King of Sorrow's first battle was not that different than Polonte's D: 2nd part was a joke because you could hit him multiple times within the same 2 seconds.
Except that Polonte didn't spin around on GODDAMN ROOF
Also, Batt's second form could instant-kill you with any attack if he knocked you into the window. Not to mention that airblast-hadouken thing that is nigh impossible to dodge
Matt Helms was hard on Mild as it is, thought. All his attacks did ridiculous damage.
