Even if we are extremely generous and assume that all 890 Pokemon are equipped with 4 moves that hit every adjacent opponent and each of those 4 moves has 64 PP (the maximum) and they all OHKO any lion they hit, they can only hit 8 lions at a time (to the left, right, in front, behind, front left, front right, back left, and back right).
8 * 4 * 64 * 890 = 1,822,720
There would still be 998,177,280 lions remaining. And again, even if we're extremely generous and assume that every Pokemon has Blissey-level HP and enough defense that the lions can only do 1 damage (the minimum) per hit, that's still only a collective 635,460 HP (714 * 890) between all of them.
Not that the lions would even need to attack. Once the Pokemon run out of PP, they'll start using Struggle and lose 1/4 of their HP every time. Even if they all have an HP stat that isn't divisible by 4 and can therefore use it 5 times before killing themselves, that's still only a collective 4,450 uses of Struggle between every Pokemon. Which still leaves 998,172,830 remaining when subtracted from the ones killed by the hypothetical high PP spread move.
A billion is just too much. The Pokemon mathematically can't win, no matter how weak the lions are in comparison. The lions can literally just stand there and the Pokemon will kill themselves from exhaustion just killing 0.2% of the lions.
