In Platinum only, the Relic Badge is the third obtainable badge, in spite of still appearing in the 5th slot in the Badge case.

===Pokémon Black, White, Black 2, White 2, X, Y, Sword, and Shield===
From Black and White onward, the main series games became less dependent on HM use gating progress and switched to a more event and flag based system. Most badges must be obtained in the listed order due to event events blocking the way forwards until the badge is obtained.
