Lol?
For each niche, I'd have a different morph (this is assuming I'm alone, in the book everyone covers something)
Battle in Enclosed/Small spaces - Lion
Battle in Jungle/Outdoor/Large Spaces - Siberian Tiger
Entry/Building Destruction - White Rhinoceros
Fast/Small Retreating Fight - Cheetah
Assassination - Taipan Snake
Long Distance/Hunting - Gray Wolf
Fighting When You Can't Lose to a Doornob/Use Weapons and Vehicles - Western Silverback Gorilla
General Bird of Prey - Golden Eagle
Fast Getaway Bird - Peregrine Falcon
Flight at Night - Great Horned Owl
Long Distance - Canada Goose
Unnoticed Flight - Dove or Seagull
Indoor/Dark Flight - Ghost Bat
Urban Camo - Tabby Cat
Freshwater - Largemouth Bass
Saltwater - Dolphin
Ocean Combat - Great White Shark, Orca
Deep Sea - Sperm Whale, Giant Squid
Insects - ****roach, Flea, Yellow Jacket, Dragonfly, Common Fly
Because I want them: Polar Bear, Grizzly Bear, Crocodile, Humpback Whale, Jaguar, African Elephant
Aliens I'd Want - Garatron (Speed), Hork-Bajir (Blades, Climbing, Intimidation), Andalite (Tailblade/Great Runner), Leeran (Telepathy). Any of Visser Three's battle morphs would be nice as well.
If I had to pick one overall morph for fighting, it would be the Tiger.
If I had to have one morph and nothing else, it would be the Golden Eagle. (I've always wanted to fly, and I'd rather not get killed doing it [Can't hunt eagles, they have no natural predators, and they, while big, don't attract attention like Bald Eagles])
Sorry if this list is obnoxiously long, I just wanted to cover everything
If anyone thinks I missed a niche or have unnecessary things, just say something. I wanted a morph so I could do anything, anywhere should I need to.
