This a variation of [this question][1] by @Gamow

Suppose there are 100 lions and 100 zebras. The lions place themselves first on an infinite plane, and the zebras are placed next. Game proceeds turn-wise. On each turn, a single zebra or lion moves by upto 100m. Lions win if a single zebra is eaten.

Note that once a zebra gets encircled by the lions, he is bound to lose. So the aim for the lions could be to create a wide ring around a single zebra.
