'With great power comes great responsibility' is a phrase often associated with Marvel's flagship character, Spider-Man. However, the Spiderman With Great Power Mug reinforces this concept but has a bit of an add on...'BUT NOT UNTIL I'VE HAD MY COFFEE'. Oh, isn't that the truth! The Spiderman With Great Power Mug is a blue mug showing off the previously mentioned phrase(s) and Spider-Man doing the web crawl thing and now we truly know what powers the Spider Sense skill...strong, black coffee...and maybe some sugar...and milk.
