Armaldo, The Plate Pokémon.
It went ashore after evolving. Its entire body is clad in a sturdy armor.Its enormous, retractable claws can cut through most anything. Its entire body is clad in sturdy plates. Its tough armor makes all attacks bounce off. Its two enormous claws can be freely extended or contracted. They have the power to punch right through a steel slab. It usually lives on land. However, when it hunts for prey, it dives beneath the ocean. It swims around using its two large wings.
Overview

Poor Armaldo. It can Swords Dance, Rock Polish, Curse, Rain Dance sweep, Stealth Rock support and Rapid Spin. The problem is that every single one of those things is done better by another Pokemon. Its a shame because Armaldo is so cool looking, and its pre-evolution Anorith is based off the Anomalocaris which easily the most horrifying yet adorable form of ancient life ever (Google it!). Its stats are solid overall, except its pathetic speed. The problem mainly stems from Armaldo's terrible typing. Rock / Bug is one of the worst typing you could ever have... comparable to even Flying / Bug. It leaves Armaldo with just resistances to Normal and Poison, both rarely used offensive types. It is weak to Water, Rock and Steel, all common attacking types (well, not so much Steel). Armaldo's great Attack stat and solid movepool are completely ruined by the terrible typing, and that everything Armaldo does something else does better. To try and use Armaldo in standard is almost suicide but in the Neverused tier Armaldo has some uses. More because of a lack of better options there, however Armaldo is a passable offensive Rapid Spinner (its rival spinners are Delibird and Spinda... not much competition). It is also usable on Rain teams to help check Grass types with X-Scissor.
