Butterfree
Butterfree across 9 games, with each ROM's own stats, sprites and changes from its vanilla base where available.
Each row uses that game's own sprite art, typing and base stats. Where a source-backed vanilla comparison exists, the changes are measured against that ROM's base game—not against another hack. Missing baselines are marked rather than guessed.
Against each game’s vanilla base
Each ROM is compared with its own original game—Crystal, Emerald, or Red—not with Polished Crystal. A game without a published baseline is labelled unavailable.
