Woobie / Ben 23: Omniforce

This includes Iron Woobies, Jerkass Woobies, and Woobie, Destroyer of Worlds.
 * Ben 23: Omniforce:
 * Ben 23 himself. He had to see his grandfather and parents brutally ripped to pieces as a child, hates himself constantly and has a huge inferiority complex which he has to hide, often breaks down when he's alone from the stress of being a leader, was forced to watch Vitiate kill Gwen (his only surviving family member) and his friends (Kevin and Charmcaster), and has a huge case of PTSD from all the war and Carnage he's seen, mainly while helping the Voth fight the Iconians. He wishes he was normal, so he and Bella could have happy lives. His inferiority complex is so bad that when he realizes that he is the most powerful Omnitrix wielder in the timeline, he vomits and faints from the internal conflict. Poor guy needs a hug.
 * Bella is just as, if not more, sympathetic than Ben. Poor girl had to see her family murdered by Vitiate, feels like the weakest member on the team, and is chased by T'ket after T'ket becomes lustfully obsessed with her. When T'Ket captures her, she puts her through a month of literal Mind Rape and other horrifying Nightmares. Even after she is freed, she has constant nightmares about it, and is implied to have lost a little of her sanity due to the torture.
 * Ashley, Valerian, Samantha, and Arthur all had their parents killed when they were young, and later had all of their crew and their entire race wiped out by T'ket.
 * Morgantine starts out as a Jerkass Woobie but becomes a Woobie as the show goes on. As Morganthe, she and her brother were orphaned at the age of 10, and had to be slaves for 5 years to make enough money to go to Wizard City. Later, Morganthe (fellow Jerkass Woobie) created Morgantine as an incarnation of all her good side just to lock her away.
 * Wrath of the Iconians:
