Superman can be a leader and a follower as has been witnessed countless times. In Justice League we've seen him lead the team in to hell and find the capability to be a team member and take commands by others. Superman is hardly anti-social and most times can inspire many to work with him in bringing down evil and horrific menaces to the galaxy and the planet.
In JLA/Avengers, Superman was granted the shield of Captain America, and in the heat of battle, if only momentarily, was able to life Thor's sacred hammer Mjolnir and wield it in combat. Respect!
Every year Metropolis Illinois holds a much beloved and highly attended Superman celebration that draws and attracts many Superman fans and children alike and even hosts many actors and actresses from Superman related shows and media. The festival is so big it's even attracted the attention of President Obama.
