What do Iron Man, Captain America and Spider-Man all have in common? They’re all Superheroes in the Marvel Universe of course. This fictional but rather wonderful universe affords each character their own unique and exciting super power/ skill. Iron Man is extremely intelligent and able to invent various devices, weapons and armour, which give him a huge advantage over his enemies. Spider-Man was bitten by a radioactive spider (ouch!), which gave him enormous strength, reflexes and the ability to cling to walls. Captain America wanted to join the army to help out in the war, but failed and so volunteered as a guinea pig, so wound up as a genetically-enhanced super-solider.
