Bastiodon (トリデプス) is the 39th Pokémon in the Sinnoh Pokédex. It is a Rock/Steel Type, and it is known as the Shield Pokémon.

Bastiodon uses the Sturdy Ability. This Ability gives it an immunity to being taken out by a One-Hit KO Move such as Horn Drill or Sheer Cold, and it also prevents it from being KO'd from an attack if its HP is full. A second Ability is available to Bastiodon from the Dream World, the Soundproof Ability. This Ability gives it an immunity to all moves that are Sound-Based, preventing moves such as Screech or Hyper Voice from working.

Shieldon can evolve into Bastiodon at Level 30.

Bastiodon is in the Monster Egg Group, and its Egg takes approximately 7,680 Steps to hatch. It takes Bastiodon 600,000 Experience Points to reach Level 100.




Bastiodon, similar to Shieldon, has a big shield for its face. After evolving, Bastiodon's shield becomes much bigger, and is armored. There are ridges along the top of its face, and there are horns sticking out around its eyes.The rest of its body also looks as if it has much more black armor, and it has gained spikes along its back.

Pokémon Information

Competitive Battling

Bastiodon finds itself to be a reliable support Pokémon in the Never-Utilized Tier of Competitive Battling. In addition to having a variety of options on the support side of things, its high Defenses give it staying power. Additionally, its Ability ensures that if it does take a hit that deals a lot of damage, Metal Sound enables it to retaliate with 50% more damage than it took. Outside of that, its low Offensive and Speed Statistics make sweeping a bad idea because those attacks won't do much damage.
