In his hut on Tatooine, located in the Jundland Wastes, Obi-Wan Kenobi describes the Force to a starry-eyed Luke Skywalker as "an energy field created by all living things. It surrounds us and penetrates us, it binds the galaxy together."
This mystic energy, which set Star Wars apart from other sci-fi franchises, continued to grow, with brand new applications of the Force being constantly added to the saga across the subsequent years since 1977.
Even by the end of the Original Trilogy, the Force had gone from an energy which can be used to choke or mind trick people, to allowing ghostly apparitions, and shooting lightning out of your hands. Despite the Force being intrinsic to Star Wars' identity, it is not always used properly by the writers, who introduce new powers into the projects that they're working on, without considering how these new abilities might retroactively damage Star Wars' galaxy, plot and lore.
Seemingly, George Lucas and Disney have crossed this line when it comes to the Force, with the two parties developing new abilities, which are either completely nonsensical, or overly strong, with it usually ending up being both.
10. Force Bellow
Perhaps one of the strangest Force powers Star Wars has to offer is Force Bellow. The ability is strangely specific, and offers no tangible use, other than allowing the user to significantly amplify their voice. Force Bellow has only been seen in legends, such as in the 2003 micro-series, Star Wars: Clone Wars, where an Ithorian Jedi utilises the power to crush building walls onto General Grievous during the Separatist invasion of Coruscant. The power was also used by Jedi Master Saba Sebatyne when reading their eulogy at Mara Jade Skywalker's funeral.
Basically, the ability is the Force's equivalent of a microphone, even though microphones have been seen frequently in Star Wars, making Force Bellow even more useless than it initially seems to be. Since this bafflingly pointless ability found its way into the then Star Wars Expanded Universe (EU), George Lucas has made it very clear that, to him, Star Wars canon does not consider the EU at all.
In an interview with Starlog in 2005, Lucas said, "that’s [the EU] a different world than my world. When I said [other people] could make their own Star Wars stories, we decided that, like Star Trek, we would have two universes: My universe and then this other one. They try to make their universe as consistent with mine as possible, but obviously they get enthusiastic and want to go off in other directions."
So, at least to Star Wars' creator, stories and powers added in the EU do not belong in the main Star Wars continuity, with Force Bellow surely not being missed that much by fans.
