He'll be as strong as any man child can be.

He's been grown up for the last 30 years or so, so his power level outside costume won't change (30-90 tons) but with his Parker Particle powered suit he'll be as powerful as Silver Surfer.

@blackspidey2099: Parker Particles?!

What on earth are those and when were they discovered :O

amazing spider-man #692 i think was when they were discovered

For once I think I thought of a clever comment, and someone beats me to it.

Now I wonder what could be his possible weakness since he has evolved into a more powerful character, unlike Tony Stark he is not dependant to technology to have superpowers and it would be very odd if he is still has no major resistance to bullets and blades.
