Ender the Xenocide's board-to-board with Brute Honour Guard

Nope, I can't say that I did. I actuallay found them on the French Halopedia: [1]

I also cannot say that are they confirmed as official images of the character. But it is confirmed that Zuka 'Zamaee is indeed one of the Sangheili in the elevator seen within The Maw. In Halo: The Flood, I recall him being the one who marked a vendetta against John-117 after he is nearly killed by him. He finally gets killed by him after stalking him across Installation 04 when he attempts to ambush him near the Pillar of Autumn's elavator. This scene is seen within Halo: CE. So I thought it would have been reasonable to include them in the article.

Where did you get the pictures of Zuka and Yayap? Did you make them? Are they confirmed images of them?
