Sigma!
I’ll probally base my character off a Pokémon from Ike my competitive teams
Name: Deimos
Species: Ceruledge
Nature: Jolly
Backstory: His father was a historian and while playing in the museum with some historical malicious armor he evolved into a ceruledge. After a couple years his father sent him to locate any historical artifacts he can find from mystery dungeons
Moves: Bitter Blade, Night slash, shadow claw, swords dance
Ability: Weak armor
held item: rocky helmet (it’s a good pair with weak armor. So the in world explanation for this, is that if rocks fall on him the helmet protects him [cuz it’s a helmet, that’s not what the item dose] and his weak armor can activate boosting his speed, also if he gets attacked the helmet dose damage back to the attacker)
Anything else: He’s studied lots of Pokémon history and is pretty smart, but he is very irresponsible
