Lionsgate

Lionsgate was a portal that surrounded and protected The Hobo Planet since it's creation 5000 years before Earth was created. It not only kept things from entering the planet, it also kept things from leaving the planet. Hobos did not mind this until the planet nearly had a nuclear melt-down that would kill everyone unless they shut down the shield. Once this was done, Hobo Cop the 2nd  suggested that they keep the shield off and create a space exploration program. These events led to Tyler The Awesome getting to the planet safely, and Hobos to travel from their planet to Earth whenever they wanted to.
