The British teenager -- originally named George Garratt -- said his new name, which is thought to be the world's longest, has so outraged his grandmother that she is no longer speaking to him, The Telegraph reported.
The teen said he used an online service to officially change his name for a mere $20 fee.
The teenager formerly known as George said he wanted a superhero themed name. Hopefully he did a Google search beforehand, because most references to Captain Fantastic relate to Gay Idol Elton John.
