While I have a small Questoris Knight House to Adeptus Titanicus I thought I should get a proper Titan Legio as the game is after all called Adeptus Titanicus...
My choice fell on the Legio Fureans, The Tiger Eyes.
I really like their colour scheme and the were deployed in the First battle of Paramar alongside the Alpha Legion that I play in 30k, Horus Heresy.

And here we have some different pictures of the beasts, they didnt turn out as good as I wanted. The light hit the miniatures a little strange I think.
All the weapons have been magnetised so I can swap around.
