Sharka stands just over 6 feet tall. His head is covered in a blue and black mass of long flexible tendrils with illuminated tips. He is wearing the white uniform of an Imperial Missionary, and has a blaster pistol and lightsaber clipped to his belt. A 3 foot long spiked and bladed mace that seems to be made from a solid piece of bone hangs from a loop on his belt.
And, yes, Sharka can turn invisible, phase through walls, talk to people in their heads, mind trick them, and heal them. He has a few more tricks, but only a couple can actually cause damage directly.
Edit: its the phase power from the clone wars book.
Lord Havelock Vetinari Avatar by AlfredAmeoba.
"A sense of terrifying admiration overcame him.
He wondered what it was like in the Patrician's mind. All cold and shiny, he thought, all blued steel and icicles and little wheels clicking along like a huge clock. The kind of mind that would carefully consider its own downfall and turn it to advantage." "Every evil tyrant has a plan to rule the world. The good people don't seem to have the knack."-Terry Pratchett
