Florent decided to become a superhero and help regulate potential threats. His name was chosen by the people and the media, which named him Thunderstrike because "English was cooler".

Some years later, his mother got a job opportunity in Gotham City and they moved out or France. Florent was saddened to leave his friends behind.

Powers and abilitiesEdit


While he already had powers before moving to Gotham, the Exobytes granted him more powerful and diverse abilities. It seems, however, that he overall possesses less raw power than other superhumans. It was presumed that this was due to his first mutation.

  • Superhuman strength : Before moving to America, he could lift and press around 15 tons. After his transformation, his maximum potential was greatly increased, and he became able to lift around 50 tons.
  • Superhuman speed : His strength extends to his legs, allowing him to outrun cars. However, he is not nearly as fast as speedsters or even others.
  • Superhuman durability
  • Superhuman stamina
  • Superhuman reflexes
  • Flight : Thunderstrike was able to fly pre-Exobytes, but this ability became more refined after his infection.
  • Heat vision : He is able to shoot powerful beams from his eyes, which go through lenses incorporated on his mask. These beams are hot enough to melt metal and can cut through steel.
  • Sonic scream : He is able to unleash a powerful scream, which, at maximum power, can render an ordinary person deaf and destroy glass.
  • Mental powers : He is able to use mental attacks. Since his mastery of this power is quite rudimentary, he is only able to launch mental assaults to inflict pain on his opponents. With enough time and focus, he can also cast illusions and to access the minds of mentally weak beings such as Solomon Grundy, and effectively shut them down.


Following his training with Batman and Robin, he developed a vast array of skills.

  • Detective work
  • Hand-to-hand combat (advanced) : He became an accomplished fighter thanks to training from Robin, and further honed his skills under one of his teammates.
  • Engineer : Batman taught him to work on machinery, allowing him to hack into computers and build gadgetry to help him in battle. He was notably able to design several suits to fight with thanks to help from Batman.
