Latios

When one thinks of Latios in Ubers, the first thing that comes to mind is power. With a decent 130 Special Attack stat bolstered by Soul Dew, Latios possesses the power to break through many of the great walls found in Ubers, such as Giratina. Latios also possesses a great base 110 Speed stat, allowing it to outrun the majority of the Ubers metagame. Finally, Levitate is a great ability that gives Latios immunity to both Ground-type moves as well as Spikes and Toxic Spikes. Latios is not without its faults, however. Pitiful 80 / 80 physical bulk means that even super effective physical attacks that do not get STAB on them will likely OHKO it. Latios also cannot check Kyogre as well as its sister Latias, as a Water Spout from Modest Choice Scarf Kyogre at full health 2HKOes it. Like most fast sweepers, Latios is vulnerable to all forms of status. Finally, Latios does not possess a powerful Fighting- or Fire-type move, meaning that it has to resort to a Hidden Power if it wants to hit Steel-types super-effectively. If it chooses to forgo Hidden Power Fire, it becomes massive Spikes bait for Ferrothorn. Despite these flaws, Latios makes for an excellent wallbreaker due to its power and Speed.
