Yeah send it to a magazine or something and my morphing team because the real world is like World of Warcraft. You need the write body for the job.
Land Scout: Red tailed Hawk or peregrine falcon.
Because their common enough and they can fly really fast. I would go bald eagle but that would attract attention.
Land Assassin: King Cobra.
I could poison or strangle someone in seconds and slither into a hole somewhere.
Land heavy artillery:T-rex
Do I even need to state a reason?
Water scout: Tuna
So common that they cant kill every tuna that they see without causing a noticeable drop in population. As long as I'm not in fishing territory.
Water Assassin: Some kind of poisonous jellyfish, if anyone can tell me a specific one it would help.
Nobody would want to get near me and if i recall one jellyfish sting gives you ten seconds to live and its about the size of your fingernail so I'd be hard to detect.
Water heavy artillery: Giant Squid
Huge, sharp tearing beak, and strong tentacles.
Air combat: Pterodactyl (you know that flying dinosaur bird thingy)
break claws and general largeness.
Tundra: Polar Bear
Ultra Strong with teeth and claws.
Let me know if you can think of any other terrains.
