All Mammals - Attack!

[Kamina]

All other mammals besides us become hostile towards humans. No advanced intelligence or world domination, just a drive to eliminate humans in their vicinity. If they do not detect humans, they'll be passive.

Can we survive?

Bonus: The same thing occurs on current Marvel/DC Earths.

The animals become hostile and immune to telepathy, and will ignore communication from heroes/villains who have an affinity/ability to speak with animals. Even people like Beast Boy will be detected and attacked no matter what form they take. Assuming the heroes/villains aren't bloodlusted and the world doesn't know what's going on, can they keep civilization intact?

[Omegalith]

Well, besides the swarms of sewer rats this shouldn't be too bad. I'll have to start carrying an anti-dog baseball bat of course.

[Omegalith]

No, wait a minute... Humans are mammals. Everyone commits suicide.

Well we'd be safe unless we go into the water. Them Blue Whales are not to be trifled with.

On land, the main things to watch out for are the big cats, Grizzlies, and honey badgers. And there's not enough of those left in the wild to really challenge ALL of humanity. Other than that, the main thing is bites and infections from domesticated pets. But there's plenty of antibiotics and rabies shots to deal with those.

Wouldn't worry too much about the Blues... They're pretty rare and their only form of attack is sheer bulk.

More worrying is Orcas, who are huge, fast, smart, sadistic and have a huge mouth full of sharp teeth.

But... but.. Free Willy!! He was so sweet!!

[Chrosis]

In the suburbs, I get my lacrosse stick and easily fend off rabid dogs, mice, rats, cats, coyotes, rabbits, guinea pigs, foxes, possums, and a whole other variety of things I can punt away.

Oh, and obese cows and the odd horse.

I'm not exactly worried.

Note that they drag the seals out into deep water, then toy with them.

[Winter Bolt]

Nothing changes, we just eat more of them.

[Hunter63]

The Mammoths rise from the dead and let a peace of advice flow to the ears of them all while we recruit the reptiles to be our slaves.

[Rhyvurg]

We win. We would CRUSH nature, grind those upstart animals underfoot and enjoy a bounty of meat. We'd BBQ for years. Because we are Man. We poison our air and water to weed out the weak. We set off fission bombs in our only biosphere. We nailed our God to a stick. Don't fuck with the human race. Humanity, fuck yeah!

[Becoming An Anthropologist]

Rats would annoy a lot of people. It would get quite nasty. Farmers would lose money. People wouldn't have pets anymore. Humanity would lose a decent junk of people, but it would never be at a level that would threaten our extinction. Rodents and such are honestly the biggest worry.
