Did you know that polar bear liver is actually poisonous and eating one will likely cause you to contract Hypervitaminosis A? It used to be a major problem for Inuits who tried it for the first time. Bear meat when improperly cooked can also cause humans to contract trichinella, which requires an expensive and highly specialized treatment regimen of either thiabendazole or mebendazole. A man named Gerrit de Veer once wrote that during his travels to Nova Zemlya that his crew had become extremely ill after consuming the meat and liver of a polar bear.
You see, we really have an opportunity with this thread to try out new type combinations and interesting designs. Ice/Fighting is a been there, done that kinda thing. It's not particularly interesting when we already have not only Fighting-type Pokemon based on bears, but also another Ice/Fighting type introduced this past generation. Ice/Dark and Ice/Fairy are a bit more interesting to me. But you know what would be really interesting to me? Ice/Poison
Beartic is a good weather nuke, being able to function in either rain or hail. However, while its offensive typing is quite good, its defensive typing is terrible. Adding Poison type gives it some sorely needed resistances to Bug, Grass, Poison and Fairy, while also removing Beartic's Fighting weakness. This greatly increases the chance that Beartic can survive, say, a Mach Punch from a revenge killer. Also gives Beartic immunity to Toxic, which can otherwise greatly reduce the length of its sweep.
So there's my idea. Anyway, it's just a suggestion, and a crazy one at that. Thank you and good bye.
