5) Doomsday
Comic Books: Famously, Doomsday is the being responsible for Superman’s demise in the iconic Death of Superman arc. In subsequent storylines it was revealed that the creature was from prehistoric times on Krypton. Doomsday – originally known as the Ultimate – is the result of numerous experiments to create a being perfectly evolved to survive the planet’s then hellish environment. Due to the horrors it’s endured, the creature is purely driven by hate and anger.
DCEU: In Batman V Superman: Dawn of Justice, Doomsday (Robin Atkin Downes) is a creation of Lex Luthor’s – a corrupted form of General Zod’s corpse, it’s based on a “Kryptonian deformity.” With its new Frankensteinian origins, the character has arguably been merged with another comic book foe: Bizarro (with a bit of Superboy thrown in for good measure). This did, however, have some precedent – the Justice League Unlimited animated series similarly depicted Doomsday as a corrupted clone of Superman.
The design of the character was also very different in the film – especially to start with. After an energy boost, the monster does eventually sprout his usual rock-like protrusions, but they aren’t as prominent as in the comics.
