The Infantile
From Destiny 1 Wiki
The Infantine is a massive Ogre in the Dreadnaught that is encountered in Summoner's Circle. The Hive are attempting to infuse it with Taken power, but Eris Morn has the Guardian intervene by summoning the Ogre early. The Infantile has a unique attack; every time its fists hit the ground, it creates the Tremor debuff, which slows down the player and prevents them from jumping. This can stack up to four times for increased duration.
