Zeke isn't really that sullen, once you get to know him. It's just his way of coping with his inability to stop talking nonsense to fill up space whenever he starts talking, because that's just how he is.
Anyway, I was quite surprised by how many people chose Zeke for the "Who would you adopt?" meme: [link]
Zeke is an awesome character, which I keep forgetting, because Zeke the doll is not exactly the same as Zeke the character. Zeke the doll gives me problems sometimes. I chose the sculpt because of the lips, which on some days just look plain odd (of course on those days, photos are crappy and won't make it here :<) For me, the sculpt is a love-hate, because I find him really like Zeke some days, and other days, when he refuses to be photogenic, I can't see Zeke in him at all. So yes. I'm quite glad he seems more like Zeke today though.
Zeke is a Leeke Khal.
