Mmmm... Personally not into the Bionicle one... I find it hard to fit into the role of a robot, I think they do have souls but still :/ Unless maybe if it were some kind of Ex Machina like AI story.. Just personal taste ^.^.............. Also, I typically stay with RPs that are pretty mature in themes, violence, death, suggestiveness with human elements....

Never heard of Azure Striker Gunvolt but I can play Anime... If you start that, let me know....
