I dont currently have any pictures of him in my phone, but an HQ I like using a lot in my Black Templars is my Emperor's champion. He's the old metal one one posed to be holding the black sword with both hands. Little background-
This model was a gift to me years back when I first bought my Tyranids collection off my friend when he first moved to Florida from Arizona back in 2012. During his transition into his job at Disney he had ran short of money and was currently living off literal pocket change, so in exchange for me wiring him a couple hundred bucks, he sent me his space bugs as well as his professionally painted Emperor's champion. I've kept the original paint on the model out of respect to him, and have played it in almost all of my 40k games with that army. During his time as my model he's beaten two grey Knight librarians, Mephiston, epidemious, a hive tyrant, a khorne juggernaut Lord, dozens of space marines and sergeants, he almost killed that necromancer character that can teleport himself and units, a few Crypteks, and almost killed a spirit seer. I haven't had a chance to play him since the more recent book came out, so mind you in each challenge I managed to score more than my fair share of 6's.
