For those of you who don't follow Hasbro's other well-known IP the Transformers, it's a show about heroic Autobots battling against the evil Decepticons.  They possess the ability to transform into vehicles, weapons and beasts.  In this series, Starscream usually serve as Megatron's second-in-command, only to plot to overthrow his master and become the Leader of the Decepticons(This usually results in him getting the tables turned on by Megatron).

However, during my day, I though "What if Starscream existed in the Equestria Girls universe not as Megatron's second-in-command, but as a student of Canterlot High?  

Description: Starscream is a male human with Black shaggy hair and grey skin with a small goatee on the bottom of his chin..  His clothes includes a Red Jacket with White Sleeves, a Black and Yellow Shirt, Blue Pants and Black Boots.

During Sunset Shimmer's days as the number one bully of Canterlot High, Starscream served as her second-in-command.  But one day, Starscream tried to overthrow her and become Canterlot High's number one bully.  IT backfired when Snips and Snails caught him off guard and he was ejected from the group.  Since then, he vowed revenge against Sunset Shimmer, only to have it taken away by the Twilight Sparkle of Equestria. 

During the events of Rainbow Rocks, Starscream was jealous of Sunset's rejection by the other students of Canterlot High, accusing her of claiming all the glory for herself.  Sunset wrote off Starscream as delusional as did the rest of her new friends.  After Sunset Shimmer help defeat the Dazzlings and regained the trust of the school, Starscream took it upon himself to start building himself up as the number one bully of Canterlot High, though he came close to losing it due to the events of Forgotten Friendship.

As he rose to power as the number one bully of Canterlot High, Starscream intimidated most students with fear even more so than what Sunset once did.  Many students are too afraid to report Starscream to Principal Celestia or Vice Principal Luna.  The seeker's spread of doubt across the students has given him a power even more so than Sunset Shimmer.  He now focuses his goal on humiliating Sunset Shimmer for revenge, and going as far as to take over all of Canterlot high.  The two that Starscream enjoys intimidating are Snips and Snails.

IT is also revealed that Starscream has a rivalry in sports with Rainbow Dash.  The seeker always enjoys a good physical challenge and does whatever he takes to annoy the young Wondercolt.  Usually, this results in a heated contest between the two.  Sometimes Rainbow Dash prevails, and sometimes Starscream wins out.

An ideal voice actor for this character would obviously go to Steve Blum, who previously voiced Starscream on Transformers Prime and Transfomers: Robots in Disguise.
