Stronger than he looks? Of course...
"Proportional strength of a jumping spider, I can handle about... one hundred and seventy times my body weight or so? Of course, that's the upper limits, tossing around the usual car or such doesn't even make a guy like me break a sweat... Though uh, that green guy who just left makes me look weak, just a quick FYI."
Hmm, where to go from here anyway? Oh yeah.
"And geez, you must be from the far future or something man. Come on, never heard of Star Wars? It's classic Sci-Fi movies right there, though really more so Sci-Fi Fantasy tha-"
Oh right they're fighting, a fact which Peter would be reminded of by a car crashing into him and sending the boy flying backward with a wince. Despite the car crash, he'd stand up and rub his head for a moment.
"Ouch... Geez, I always do that in these kinda matches ya know? When there's an actual danger to be dealt with focusing is a lot easier, but not so much here."
This time as the car passes by he'd dart, aiming to get down low and make himself a smaller target while moving toward the thing. Assuming it kept on course, it would soon have a spider under it. Who'd then slam both his palms up and send the car flying up into the air, before aiming a quick web line toward Carl's right leg and aims to pull the man down if it hits.
