Heatran

Heatran fills a unique niche in the Uber tier thanks to its stellar typing and monstrous Special Attack. Heatran retains its role from the OU environment by toasting opposing Steel-types that stand in its way, as well as stopping any offensive Shaymin-S not packing Earth Power, something not a lot of other Pokemon can claim. Heatran also resists or is immune to four key attacking types commonly found in Ubers: Fire-, Ghost-, Dark-, and Dragon-type. While it may be literally scared to death by the ubiquitous Kyogre and the tiniest of earthly tremors, Heatran functions well in the Uber tier when partnered with Groudon and its ever-lasting sun. However, don't expect it to be able to take too much punishment.
