Who would win? Every Pokemon or 1 billion lions?

I believe that in a fight between a billion lions and every Pokemon, the Pokemon would win. I say this because there are certain pokemon that are basically seen as a god. For example, Rayquaza is seen as a very powerful pokemon. Some pokemon can into space and even different dimensions. During the fight, the small, weak pokemon will die almost immediately. But, some of the weaker mons can fly or dig underground like Pidgey or diglet, avoiding the lions.  Also, some big powerful mons might a special type that can slow the lions. For example, Volcanion and Heatran are fire type and for a lion to touch them, parts of the lions' bodies would burn causing them to be weaker and slow the lions down. Also, there is a certain Pokemon that can possess living things and poison them. The pokemon is pecharunt and it can possess people and living things and the mon is a poison type which, like many other mons, can slowly kill the lion. Also, when in a battle inside of one of the games, certain pokemon can put affects on their opponent and can stop them from attacking or can slowly kill them. They could either paralyze them, which makes them not move for certain turns, sleeping, which prevents attacking at all until awoken, poison, burned and many more. And in games, the trainers can give the affected mons berries or potions to help them but it is a battle of wild pokemon and wild lions so berries and other healing things wouldn't be used. Although a billion lions is a lot, certain mons can easily get rid of a lot of them. For example, some ghost type mons can scare the lions so bad were they could, hypothetically, be traumatized and would affect them during certain battle. Also, the pokemon Lugia, its said in its dex entry that it has caused 40 day storms and really high speed winds and hides underwater to prevent damaging things. Lugia can easily blow away a bunch of lions and depending on how many times he flaps his wings, he can cause hundreds of hurricanes. But, this isn't including pokemons actual movesets. a popular water move called surf, can do over half of the opponents team in one use depending on the timing and place. And although overtime the pokemons could start to die and the powerful ones are slowly following too, some pokemon can send the lions into space. For example, Hoopa, a mythical physic pokemon, can open a portal with his rings and transport himself or others through it. In his ddex entry, it says legends of its avarice tell how it once carried off an entire castle to gain the treasure hidden within. Also, the pokemon Giratina, can open an alternate dimension and can trap himself or people in their. So, worse case scenario, one of them can constatly keep transporting the lions until there are no more and the they die either because of no oxygen or starvation etc. So, I believe that in a fight, every pokemon would win.

I believe my opponent may not have grasped the scale of 1 billion lions. Like with a billion of anything, 1,000,000,000 lions is a very difficult amount to conceptualize.

So, in an effort to better our understanding of this number, let us begin with 10. A row of ten lions standing in front of you certainly ordinarily wouldn't be a welcome sight outside of zoos, but for dozens of deific mons, there would of course be no contest.

Then let us imagine ten rows of ten lions. A centuria of lions would of course be a terrifying sight to us. But still, to these mons, we can expect them to worry more about what they'll have for lunch.

Then let us imagine 10 of these miniature armies of lions in a line. I have no doubt the only issue for the mons would be the resulting PETA lawsuit.

Even adding 10 more of these lines of miniature armies brings no significant difficulties, I'm sure, as we've only just matched the amount of Uruk-hai sent to invade Helm's Deep. Still, we've barely scratched the surface on one billion and we're already witnessing a large lake of golden fur.

Ten such lakes should be able to surround the mons for as far as the eye can see in many situations.

And I think if we multiply that by ten again, an ocean of teeth and claws should be a good description. Should the mons ever make a fatal mistake (as it seems likely many would in the duration required to clear out one million lions, even with the abilities mentioned by my opponent), they would be devoured in mere moments. 

Now we can take that one million lions, enough to cover every bit of land around you even in a very large, flat place, and we can multiply it by ten again. These mons must then deal with such a massive army ten times over, plausibly extending the battle for hours, exhausting and demoralizing the mons who stayed alive and witnessed so many of their comrades die. The lions who are slowed, paralyzed, possessed, poisoned or weakened would be trampled and used as the new battlefield by the many, many thousands of lions waiting to get in on the action.

And we can multiply it by ten again, and again. The battle would take days, and flying mons would begin falling out of the sky from exhaustion. Those which are underground or in space would either have to come back at some point or face that the mons, as a whole, have been defeated, despite their narrow escape.

Now is where things get interesting, what counts as a lion? Surely a trained lion would still be a lion, as would one with a prosthetic limb. There's nothing in the debate descriptions precluding these lions from being cyborgs, enhancing their abilities in fantastic ways. Of course we could say the same of the mons, but there would be many, many more lions than mons, so this would likely still benefit the lions a great deal.

As for the abilities that can supposedly easily get rid of the lions, we need specific stats to understand what effect they would have on the overarching battle.

I waive this round.
