More mutant wildlife

I know there are threads like this already but I can’t seem to find them.

Playing Fallout recently has left me somewhat underwhelmed by the variety in wild animals. In particular, there aren’t any reptiles other than Deathclaws. Iguanas are implied to exist, but as far as enemies go there aren’t any giant lizards. Fallout 2 added geckos, which I’ve always felt looked kinda stupid. So this got me thinking of some giant varieties of reptiles that wouldn’t feel out of place in the first game:

Pit Vipers were obviously planned at some point, to be worshipped by the Vipers. I imagine these would’ve been man-sized rattlesnakes (what other vipers exist in that region?).

Gila Monsters seem like an obvious one, being featured in a famous 1950s B-movie (though they wouldn’t be THAT big). They’d have to spread out a ways to be found in California, but I imagine the geographic ranges of surviving desert species would expand in the wake of the War. These guys would be mostly found in caves and mountain encounters.

Horned Lizards, also called horntoads or horny toads, look pretty cool and already have some species in California. Maybe they could be given forward-facing horns for attacking.

I then started thinking non-reptilian wildlife that could be added, because why not? First, let me get two out of the way that appeared in later games: ants and cockroaches. These seem like such obvious choices (ants are featured in another famous 1950s monster movie and roaches are the stereotypical nuclear war survivors) that it’s almost surprising that they aren’t already in the game. Anyway, some others I thought of:

Grasshoppers (maybe call them sand-hoppers now). If mantises can survive the war, why can’t these guys? Maybe because they’re herbivorous and aren’t related to cockroaches? That’s fair. Still, I think dog-sized grasshoppers would look cool, and imagine how much ground they could cover per action point? It’d be hard to escape from these guys.

Jackrabbits, also called hares, would be another very fast creature. Maybe give them antlers and call them jackalopes? This would be another herbivore, but they can still be aggressive and dangerous.

Donkeys, or burros, would round out the herbivores. Irwin had a donkey but we never see it except for the pile of bones that are identical to the “horned kangaroo” found elsewhere in the game. I think donkeys should be a rare alternative to brahmin. Like dogs, they wouldn’t really be mutated at all.

Kangaroo rats, being desert-adapted natives to California and the southwest, would probably be more likely candidates to survive the war than rats and moles. I’m also thinking they might be the true identity of the mysterious “horned kangaroo” skeletons (though these are likely just mono-headed Brahmin). Kangaroo rats would be larger and more kangaroo-like in general. And also maybe have horns?

Two-headed bears, mostly just as a reference to Fallout 2 and the NCR flag. I do think bears could have a survival advantage due to their hibernation periods and omnivorous eating habits. Still, it’s kind of a stretch. I’d limit these to very rare encounters.

And now I feel I’m starting to drift away from animals that would fit Fallout. Anyone else want to chime in?

I'd imagine a Komodo dragon would fit in nicely as it's already a large beast. Adding a sprinkle of raditation would mutate it good. Hell, dip it in FEV and we got a pet for super mutants.
 
I was trying to limit this to animals that are found in or nearby the region, but on the other hand, apparently Radscorpions are descended from North American Emperor Scorpions… despite there being no such thing, as Emperor Scorpions are native to Africa. So I guess Komodo dragons could work. I was thinking Gila monsters would be Komodo-sized due to radiation and could sort of fill that niche.
 
They can be found at zoos, seems to be at least a dozen in the states spread out. Wouldn't take much too see that population transferred to the west coast. But yeah, I get your point.
 
rat king
he is giant rat, as big as the lesser mole rat, with multiples heads 3-7 merged around the skull or the cervical part of the spine, with some of them being inside the body and only shows eyes or jaw, teethe

Sounds cool but I'm confused, is this just one mutant rat or an entire species of them?

what do you think about using "foster rule" and making giant dinosaurs chickens or maybe birds as origin for Therizinosaurus like mutant

Only as special encounters IMO.

*Recall that the devs had plans for the PC to encounter their S'Lanter, but chose to omit them as too far off; it didn't fit in.

I think that would be cool. We could use more avian creatures. But I’d like them to look a little uglier. Maybe make them featherless or something.

I also had an idea for bald, flightless vultures that would be similar.

I thought the S’lanter were removed mostly for being anthropomorphic talking raccoons. I don’t think a mutated raccoon would necessarily be out of place as long as it was just another animal.
 
The discussion is about thirteen foot tall pigeons, is it not? The S'lanter were also cut simply for being too much added work, with not enough time to do it. A dev quote mentioned them [loosely] as not really fitting the narrative.

Myself, I have no problem with extreme examples of mutated fauna, but rare, and only in the wastelands; never in or near towns (as a serious and accepted fact of life).

Right, I was just comparing giant raccoons with giant pigeons as similarly “mundane” (as far as what’s acceptable for Fallout). I suppose 13 foot tall killer pigeons would be a bit too extreme, but only because at that size they’d rival deathclaws. But as far as mutant pigeons go, I don’t think a 4 foot tall one would look too out of place.

aren't deathclaw in lore 12 foot tall in lore? we don't see this because they are quadrupeds, with their arms being well evolved unlike their legs like gorillas, well before bethesda changed it
 
I really don’t know how tall they’re supposed to be. I guess 12 feet makes sense. But they seem bipedal to me.
no they are quadrupeds, their arms have more muscles mass and duple the size than the legs, and in targeted shot you can see that

and in van buren their module is quadrupeds

and it looks identical to the original

and if you give their sprites a look you can see them walk quadrupeds

it seems that they attack with one hand and use the other to stay balanced
but in fallout 2 goris have sprites when he run on his two legs so (wait why didn't they use it for regular deathclaw?)i am sure they can be bipedal
