Jen Cobroch is a sophomore at Hope's Peak High and a high ranked gatekeeper. She is known to be bratty, stubborn, seductive, devious, and cunning. Jen was a major bully towards her younger brother Railo Cobroch, and always gets what she wants through acts of mischief. She's also a player when it comes to Gatekeep Battles, often emerging victorious. Jen is always cocky, and has no trouble showing it either. She challenged Victoria to a bet that if Jen wins, she gets to have Babi to herself, since Babi is a highly ranked unit above the others. Despite an epic battle between the two and their units, Victoria emerges as victor. Upon seeing this, Jen shows a sore loser attitude when she lost, claiming that Victoria cheated secretly using one of her strongest despite using only her weakest AGAINST Jen's strongest units. However, Jen was eventually called out as a fraud when evidence of her cheating eventually got brought to light, and thus being labeled a sore loser since she doesn't even know when to accept defeat. Jen became very bitter towards Victoria for ruining everything (first world problems), but subsided after witnessing Railo bludgeoning their mother to death because of all the abuse he received and the love and treatment his own siblings are receiving. Jen parted ways with her behavior and decided to start anew, becoming best friends with Victoria and her friends.
