If youโre a Marvel fan visiting the Disneyland Resort, Avengers Campus is undoubtedly on your to-do list. But donโt race in too quickly, or youโll breeze past a hidden gem right at the landโs entrance: the arc reactor.

For the uninitiated, the Arc Reactor is the crown jewel of Tony Starkโs genius. First glimpsed in Iron Man (2008), this energy source was initially created to keep shrapnel from reaching Tonyโs heart and later became the clean power supply for his high-tech suits. And the campus has its own massive arc reactor just off the Buena Vista Street path, surging guests with energy as they cross into the land.
Another added bonus: Avengers Campusโ backstory is that it was built on a former Stark Industries complex. So Tonyโs own technology is now build into the ground as well, alongside his fatherโs.
