Logo/T-shirt Design for an Obstacle Course Race (OCR) team: "Orca OCR"

Were looking for 3 designs for a new OCR team that we can apply to our team page and produce merch for our members. We are looking for one general logo including the team name and an ORCA, the apex predator of the sea. In addition, we would like two different t-shirt designs: (1) we would like one where an orca is wearing the armor of a spartan warrior just like the ones worn in the movie 300 [this is because we participate primarily in spartan races] and (2) whatever you think would look great, were offering you creative freedom; our only contention is the orca must look aggressive.
