Dyna Brothers (ダイナブラザーズ) is a 1992 strategy game by CRI for the Sega Mega Drive released exclusively in Japan. It was followed by Dyna Brothers 2.

The game is a real-time strategy title. The player must guide an army of dinosaurs to victory against their opponents, who are aliens that have invaded Earth. The player's main base and source of life is "The Egg", from which other life forms are spawned. The enemy's base is represented by a UFO. Players have the choice of creating over five different types of dinosaurs: a stegosaurus, triceratops, tyrannosaurus rex, allosaurus, and lastly, an oviraptor. The player uses each dinosaur's unique ability to gather power points to spend in executing commands. This includes sending rain showers to grow vegetation, causing disasters, giving specific directions, and so on.



  • Sutego (ステゴ) -- Stegosaurus. The player's initial character and an herbivore. He eats grass to gather more power points for the player to spend on using commands. His specialty is laying eggs.
  • Torikera (トリケラ) -- Triceratops. Herbivore with emphasis on endurance from enemy attacks.
  • Tirano (ティラノ) -- Tyrannosaurus Rex. As a carnivore, his focus is on attacking enemies and eating them. Slow, but can travel long distances.
  • Aro (アロ) -- Allosaurus. Like Tirano, he deals in attacking as a carnivore. Fast, but moves in smaller increments.
  • Pii-chan (ピーちゃん) -- Oviraptor. The sole ovivore (egg-eater) of the game. He is weak in strength and defense, but is very agile. His specialty is to find and swallow enemy eggs before they hatch.
