Return of UltramanEdit

Dr. Mizuno, a scientist that pushed the boundaries of biology and an old friend of Hideki Go, wanted to mix animal and plant DNA for science. The result was the monster Leogon, who was born from an egg in his laboratory. However, something went wrong, as Leogon quickly escaped and grew from two feet long to the size of a rhinoceros within a minute. MAT quickly tracked Leogon down to a lake where they attacked him. MAT did little except annoy the hybrid organism as his vines easily entangled them in midair. Hedeki wanted to end the madness before someone was killed and quickly turned into Ultraman Jack. The two giants clashed, but Jack quickly outmatched Leogon and finished him off with the Ultra Spark, slicing him to pieces.


Powers and WeaponsEdit

  • Growth: Leogon can grow from two feet long to 157 feet long in a matter of hours.
  • Adept Swimmer: Leogon can swim through water at low speeds.
  • Vine Tentacle: Leogon can use two large vines like tentacles from the tubes on his back. These tentacles are ideal for wrapping around targets.
