is a well-known, albeit controversial, ROM hack of Pokemon Fire Red . The name "Untevo" plays on the idea of evolution reversal. While most games push monsters to evolve into stronger forms, Untevo explores what happens when evolution is undone, corrupted, or twisted sideways.

While the "Ntevo" misspelling will continue to confuse search engines, the spirit of the hack—evolution run amok—lives on in newer, more stable projects. If you do manage to secure a working copy, treat it like an archaeological dig: expect bugs, appreciate the creativity, and remember to patch your own ROMs.
