The Energon Pub

Trying to figure out who to use as Grindcore for my 'Dead Universe' display.

Thoughts?

if you're up to painting, ROTF Scattorshot or HftD Firetrap have similar looking Altmodes and bot modes.

Otherwise, give the Energon tank drones a look, i think one of them is a green shade close to Grindcore.

Have you considered Universe Hardhead?

Tough, green, tank-truck with guns on it. Seems to fit the bill IMO.
