I vaguely remember this being considered controversial or bad writing... This was regular Spiderman (black suit was Black Cat's not the alien symbiote)
Considering Spidey's lifting power 20 tons... Firelord 50 tons. (it isn't the staggering difference you'd find between characters in DC). With Spidey's speed advantage, it doesn't seem that far fetched at all. Especially with all the success Spidey has had against Titania.
