Pft, Punisher has hanged with the very best, Daredevil, Captain America, Wolverine etc. etc., hence, this second stringer -who by the way, got owned by Azrael, lols-, gets gutted.
Punisher usually had something better then a knife, and when he didn't he had some pretty heavy PIS (Like his fights with Bullseye, where he starts off with an advantage, then blows it by gloating and giving Castle openings.)
And Bane since destroyed Azrael, without the venom.
Who has Bane beaten who is worth his own body weight? He just crippled an exhausted Batman and proceeded to get his sh*t pushed in. He is good, don't get me wrong, but not as good as those Frank has faced.
If you mean because I left some facts out, I forgot about Azrael being on Venom.
...or if you mean what I said about Punisher, it's all in your Respect thread. He did use a tranq gun against Daredevil, a gun against Spider-man, and both h2h fights against Bullseye started out with Frank on the recieving end, Bullseye stopping a moment to quip instead of pressing the advantage, and Frank leveling him.
Actually a knife in the right hands is probably a worse matchup than a gun for bane. Bullets can be ignored supposing they don't hit anything vital. But hamstringing somebody is a surefire way to stop someone from walking.
