exactly, talibak took on batman in one of the justice league episodes, and supes vouched for bats saying that bruce would have taken him down.
terry is pretty much as close (in his adult peak) to brue as anyone is ever going to get with tons of experience and two generations of input behind him.
alright, let's look fairly at the strongest person spidey has face in the animated world. hmmm... perhaps venom, or the rhino. I'm pretty sure bane or mad jack would give them a run for their money.
PLUS AN IMPORTANT FACTOR, terry fights dirty and doesn't care about how he gets the victory, nor does he rely on wit for the majority of his time but he has that in his skills as we see against the joker. he is also used to going up against wise crackers like the joker so he knows how to handle spidey's quips while spidey wouldn't be used to being on the receiving end of banter.
I mean who else has the balls to laugh in the joker's face
what honestly did animated spidey ever do/show in the series that really was that great?
