This is part of a series I'm doing called Justice League of Nintendo.
When he was an infant, Luigi was sent to the real world with his brother Mario
to be safe. Luigi was too young to be effected by the move and as a result didn't develop powers like his brother. However one day a ring fell out of the sky and took him to a dying alien who informed him that he was chosen by the ring to be the new protector of this part of space. Luigi donned the ring which gave him amazing abilities and became the Green Lantern. It wasn't long, however before he realized that some problems were to big for one hero alone so he joined his brother in the Justice League of Nintendo.
