The cover monster from Pokemon Sapphire, Kyogre, will disappear from the mobile game today, February 14, making this your last opportunity to catch one if you still haven't. >Like most other Legendaries to appear in Pokemon Go thus far, Kyogre can only be encountered as a Raid Battle at Gyms. You'll first need to battle and defeat the Pokemon before you have an opportunity to capture it. As one of the most powerful Water-types in Pokemon Go, players will want to bring Electric- and Grass-type Pokemon such as Jolteon, Zapdos, and Exeggutor to gain the advantage over Kyogre.
