How many Pokemon would be need to defeat 1 billion lions

Just one Tinkaton,

And if the lions are pokemon forums user, just one talking of something non pokemon they’ll basically implode at that

I think I only need one Ceruledge honestly

It can jump into Phantom Forces and attack when least expected with literal swords!

Stab stab stab win

Plus if it gets hit Bitter Blade can recover it

But Bitter Blade is Fire

If we're only using Top-Tier Pokemon, I would say 1 billion Boltund. The rest are posers anyways

I don’t think one ceruledge could beat 1billion lions though
