Bizarro Superman
Journalist
King of Bizarro World
Htrea the Bizarro World
Note: Htrea is Earth spelled backwards.
Below average intelligence.
Note: Bizarro's imperfect memory give him a warped outlook on reality and he tends to think and speak using reverse reason. His fighting skills are clumsy and powers are occasionally erratic; resulting in cold vision rather than heat vision or X-ray vision that can only see through the element Lead.
Only known weaknesses are to imperfect Blue Kryptonite radiation, Kryptonian viruses and magic.
Kryptonite is a radioactive element native to the extinct planet Krypton, and depending on its color qualities, effects Superman and Bizarro in different ways. Blue Kryptonite although deadly, in small amounts grants Bizarro 12th-level intelligence. Green Kryptonite is harmless.
The Kryptonian virus Xarxas which causes havoc with the mental reason and abilities of normal superhuman Kryptonians has the opposite effects upon Bizarro making him more logical and able to control his powers, but presumably the virus will eventually result in coma and then death.

Luring Superboy into the ray, Luthor created an imperfect duplicate which roughly resembled the Boy of Steel and possessed all his powers, but none of his mental capabilities. Feared and despised by the citizens of Smallville they referred to the creature as bizarre, prompting the simple-minded creature to name itself Bizarro.
