Armaldo

Armaldo is one of those Pokemon that gets less use than it deserves. With great offensive typing—only Steel- and Fighting-type Pokemon resist both STABs—and a base 125 Attack, Armaldo has the power to rip through unprepared teams. It also has a niche over other Bug-types thanks to access to Swift Swim via Dream World, which makes it a great physical attacker in the rain. Moreover, unlike other Swift Swim physical attackers, such as Kabutops and Qwilfish, Armaldo can take care of Pokemon such as Latios, Cresselia, Latias, and other Pokemon that tend to give rain teams trouble. It also has great defensive typing as well; with only three weaknesses and 75 / 100 / 80 defenses, it'll be on the field for a while. However, it isn't all raindrops and gumballs for Armaldo. With weaknesses to the common Water- and Rock-type attacks, the former even receiving a boost under rain, Armaldo will have problems executing its offensive role properly. To make matters worse, its low base 45 Speed makes it dead weight against other Swift Swim users such as Ludicolo and Kingdra. However, Armaldo isn't a Pokemon to be underestimated, as it has enough weapons in its arsenal to wreak havoc.
