A brood of three Tyrant Guard that I added to my splinter fleet, as well as the ancient Hive Tyrant model that they will be protecting. Seriously, that Tyrant model is at least 12 years old.

The guard are mostely just ablative wounds added to the Tyrant so that it lives longer, but they aren't too shabby in hand-to-hand themselves. A very scary unit to face. The best part is that it can be made even more scary by supporting it with some specific other units; units that I'll post in tandem when I get them put together.
