Phoenix Logs/Banished Units/Blisterback

From Halopedia, the Halo wiki

A heavy air unit that launches barrages of plasma missiles.

The tick-like Blisterback is a massive aerial siege vehicle developed and built by the Banished. It is designed to alternate between two modes: On the ground it deploys to fire Annihilator siege missiles. and While in the air it fires medium plasma cannons that can engage ground and air targets.

On the ground the Blisterback enters a lockdown mode, stabilizing itself before its carapace splits open, revealing a battery of long range rockets. It can then exit lockdown mode to become airborne, closing the rocket carapace and tucking its legs underneath its body to perform a vertical take-off and enabling the use of its medium range plasma cannon to bombard the enemy.
