Belepheron's eyes widened as the diminutive creature landed in front of him. Orks weren't known for their explosive expertise, in truth they just crammed as much explosives that could fit and that could prove problematic to even holy Astartes power armour. With little time to react, he moved on instinct. Two swift steps brought him to the creature. The second following through to place a kick in the grot's chest. Sending the pathetic creature sailing along the corridor to impact comically on the for wall, before falling to the ground.
