is a purple colored Lasher boss. It is roaming the ramps at Brimstone Lake Water Refinery
. It is rumored that Esoobac
has a taste for Telemetry Matrixes
, and that it could be the cause as to why the Brimstone Lake Waypoint
malfunctions now and then.
You need to kill it as a part of Thunderhead Targets of Opportunity objective "Kill All 9 Thunderhead Named Bosses".
It is likely that Esoobac is a tribute to the Red vs. Blue character Caboose. Both characters are approximately the same color purple.
