Oh my god, all I can think of is your characters being like, the last ones created, and the scientists were both bored out of their minds and running on five seconds of sleep, so they just decided, why not, and smashed a bunch of non-combat animals into the more dangerous kind. Just to see what happened.

These animals are all totally dangerous. A scorpion with a harbinger of death? Totally dangerous. A freaking mongoose with an eel that has rows and rows of sharp teeth? Definitely dangerous. A snake that can spit venom with a canine that steals/eats babies? Very dangerous.

I mean, traditionally non-combative. Nobody thinks about eels or aye-ayes when they think 'this will kill you, don't poke'

I mean, true. But these are scientists! They should know that these creatures can be extremely deadly!

Well, sure, but not really animal scientists. Genetics and biology, mostly, with a heavy focus on military application. SO, they're gonna go for the biggest, deadliest, and/or scariest monsters they can.

But what about the animals they need for more slippery missions, I dunno but a snake or eel seems like a good idea to me then. Besides, if one of the scientists are australian then that would easily explain the dingo. Plus, I'll have you know that I chose the best scorpion for this. Other than the deathstalker, but I mean, I loved the Spitting Thicktail Black Scorpion way too much to say no to that one.

Sure, stealth missions are a thing, but consider; genetically altering a group of fetuses (Fetii?) is probably MEGA expensive. And I'm pretty sure financial backers would be more focused on the frontal-assualt possibilities. It would be easier to see conclusive results on the validity of the experiment, because they can observe the targets a lot better out in the open, as well as look at the bodies left behind.

Whenever government funding occurs though, they don't fund only certain things. The would've funded the experiment as a whole, so it would've been up to the scientists what they did. Besides, you can't tell me that my hybrids aren't going to be awesome in fighting action.

Not that, I mean specifically stealth-focused hybrids. Like, uh, a chameleon and owl, maybe? That seems like a very sneaky animal hybrid. Even if it was scaled up to human-sized, which they would probably try to avoid just because a smaller animal means less to see, but it would NOT be good for direct combat. Chameleons don't have any kind of offensive adaptations, and owls have hollow bones to help with their flight. Even if the hybrid ended up as a mostly-owl creature but with active camoflage, it still wouldn't be good for much else beyond scouting and stealth. 'Cause, sure, sharp talons 'n all that, but the animal form would probably have wings instead of arms, and guns were not meant to be shot from your feet. Especially not bird feet.

True, true. It's a good thing that all of my chosen hybrids would technically have hands then. The only one that probably won't is the snake and dingo one, since neither of those don't have enough hands for that stuff. I bet a mongoose could hold a gun though, and aye-ayes definitely could. Sooo, they're gun friendly.
