Is it just me or does Xol seem like a budget Gravemind from Halo? Like the whole screen shake/blur when he is speaking reminds me of the mission "Cortana" where Master Chief goes into high charity to save Cortana. Now it is a guardian saving rasputin.

Weirdly he looked like some old Gravemind concept art I've seen. Though he still looks like a giant Graboid.
