Alfie Owens
From Tardis Wiki, the free Doctor Who reference
Alfie was the son of Craig Owens and Sophie. Although he liked the name Alfie he preferred to call himself "Stormageddon, Dark Lord of All", and referred to Craig, as well as The Doctor, as "Not Mum". His crying gave Craig the power to overcome his conversion into a Cyberman . After this event he referred to Craig as Dad instead of just "Not Mum".
