Trojan is a status effect introduced in Bloons TD 6 characterized by a Bloon being unable to spawn any children bloons even if it is not a Red Bloon. Upon the affected bloon being popped, it leaves no trace of its presence.
Trojan is represented on the Bloons Wiki with 
, which depicts Benjamin at Level 7-9, who can inflict this status on a bloon.
There are only two sources that can inflict Trojan status effect in Bloons TD 6. Both of them are single-target Impact 
attacks. One of them is Benjamin's Bloon Trojan attack, which he unlocks once he reaches Level 7. It affects a random bloon on screen which can be up to and including a MOAB. Trojans can be inflicted on BFBs and DDTs as well when Benjamin reaches Level 18. The other source of Trojans is Ezili's MOAB Hex ability, which adds Percentage Damage 
in addition to the Trojan status onto an unfortunate MOAB-Class Bloon. Unlike Bloon Trojan, MOAB Hex only targets blimps, and its targeting is controlled by Ezili's Target Priority. Additionally, it can wear off if a blimp is lucky enough to still be alive at the end of the ability's active period; Bloon Trojan in contrast never wears off. Ezili's MOAB Hex is considered a true Trojan due to inflicting a similar behavior to Trojan, and the attack also has the MOAB Hex 
status effect to indicate which blimp is currently affected by a Trojan-like effect.
Trojan automatically has Penetrates Blimp 
, and conveniently enough both of the only sources of such can affect MOAB-class.
