Only 6 of 9 playable characters have "Ultimate Weapons" (max stats, unique models). Cait Sith, Vincent, and Cid use standard weapons with maxed Materia slots instead.
| Character | Weapon | Location / Method |
|---|---|---|
| Cloud | Ultima Weapon | Diamond Weapon drop (Disc 2/3) OR Gold Saucer Battle Square (32,640 BP) |
| Barret | Missing Score | Corel Reactor (Disc 2) — after Huge Materia quest, examine reactor core |
| Tifa | Premium Heart | Wall Market (Disc 2/3) — talk to man in back room after Sector 5 reactor |
| Aerith | Princess Guard | Temple of the Ancients (Disc 1) — chest in clock room (missable after Disc 1) |
| Red XIII | Limited Moon | Cosmo Canyon (Disc 2/3) — Bugenhagen's machine after Huge Materia |
| Yuffie | Conformer | Wutai Pagoda (Disc 2/3) — defeat Godo (her father) in 5-floor challenge |
Materia growth (AP) matters more than weapon base stats. Slot Master Materia (Command, Magic, Summon) into 8-slot weapons for true "ultimate" builds.
