Brilliant Diamond & Shining Pearl Pokedex

Chibi art style on Switch, the Grand Underground with encounter rooms, a buffed Cynthia with competitive items and smarter AI, auto Exp. Share for the whole party, and quality-of-life improvements like HM replacements. No Mega Evolution, no Dynamax. Faithful remakes with the same story and regional dex.

Chimchar for the same reason as the originals: Sinnoh has almost no Fire types. Infernape is fast with mixed offenses (104 Atk, 104 Sp. Atk) and Fire/Fighting coverage. The Grand Underground helps fill team gaps, but starting with the rare type is still the smartest move.

An expanded version of the original Underground from DP. It adds Pokemon Hideaways: themed rooms where you can encounter Pokemon not normally available on the surface. Types depend on the statues you've placed in your Secret Base. It opens before the second gym and is the main way to fill team gaps early.

Gen 8, Switch, 2021. BDSP are Diamond and Pearl remakes developed by ILCA (not Game Freak). The roster caps at 493 Pokemon across Gens 1 through 4. No Mega Evolution, no Dynamax. Faithful to the originals with the Grand Underground as the main addition.

Yes. Her team has perfect IVs, competitive held items (Leftovers, Sitrus Berry), and smarter AI than the originals. Her Garchomp still leads and hits like a truck, but the rest of her team is better optimized too. Many players consider BDSP Cynthia the hardest champion fight in the series.
