COBRA (BTD7)

The COBRA is a tower in Bloons Tower Defense 7 that has been altered to fit with the singleplayer tower defense. He still wields a gun that can pop two layers with very low pierce but like in Bloons Adventure Time TD and its second counterpart, he can call in cash and med crates that give cash or regenerate lives. He costs $540 on easy, $600 on medium, $660 on hard, and $720 on Impoppable. His ability sends the strongest Bloon in his range up to a Ceramic backwards for 10 seconds. When the timer ends, the Bloon continues forward from its location at that point. Tier 5 allows the ability to send back anything up to BFB and DDT and sends backwards for 15 seconds. Tier 6 allows the ability to send back anything up to BAD and sends the strongest Bloon in range all the way to the entrance. The ability is the only ability in the game with a cooldown that can vary, with the cooldown being longer if a stronger Bloon is sent. The cooldown goes from 6 seconds if a Red is sent back, up to 120 seconds if a BAD is sent back. The other Tier 6 upgrades can use a "thunderstorm" attack that can fire extreme-pierce forked lightning with every hit or lower the rank of every Bloon sent up to a ZOMG being affected (i.e. it can not lower BADs or higher).
