The explosion of the Distant Star not only caused the rain of Stardust. It also opened thousands of portals all over the universe. Kodama has arrived through one of those portals. He comes from a planet covered by blue vegetation where the evolution of life works at a very different pace to that of Monster Legends. This is reflected in his Cosmic powers, which allow him to play with the pacing of everyone around him.
Kodama is a Nature Controller with Cooldown Activation skills. He can also apply Nature Weakness, Daze, or Poison to enemies or Torture Immunity to allies. He has an Evolving Trait: at rank 0, he's Immune to Poison, at rank 1, he blocks enemies' resurrections and, at rank 3, he gains Torture Immunity at the start of the battle.
