|Dromaeosaurid Theropod Grundalychus|
Grundalychus, otherwise known as the Grundal, were Dromaeosaurid Theropod's that roamed Ninjago before extinction. One Grundal briefly menaced Morro before he was saved by Sensei Wu, which the Master of Wind took as a sign that he was meant to be the Green Ninja. A Grundal was known to have been resurrected by Lord Garmadon. He did so by bringing its skeleton, which was stored in a museum, back to life using the Mega Weapon. When the potion was used, the Grundal was sent back to his own time, meaning he was destroyed at the present.
Grundals were said to have hides tough enough to withstand ordinary weapons. They were also nocturnal, hunting at night, rumoured to only be destroyed with light.
