Overdant Monitor

When geriatric gardeners get serious, they suit up in vines, roots and rocks and shoot needle-carrying wasps at you. Aside from the normal 'space marine' suit, there's a spiky Bramble configuration for ramming into crowds and the highly-armored but slow Cromlech configuration.

A train-of-thought following a druid character commission I did while having a Starcraft 2 longplay for background noise.

Overdant = Overseer + verdant
