Tega Sword Yellow (Japanese: テガソード イエロー) is the personal giant-robot form of Gozyu Tyranno (civilian name Ryugi Bakugami), the Yellow member of the five-person team in "No.1 Sentai Gozyuger" (ナンバーワン戦隊ゴジュウジャー). The show aired on TV Asahi from 16 February 2025 to 8 February 2026 and is the 49th Super Sentai series, produced during the franchise's 50th-anniversary period; within the story the team is styled as the "50th Super Sentai." Gozyu Tyranno carries a Tyrannosaurus motif, is the team's powerhouse, and wields the Tyranno Hammer 50. The plot begins with the sentient sword TegaSword choosing five social outcasts to gather the Sentai Rings scattered across the cosmos.

The TegaSword serves both as the team's transformation device — a gauntlet sword that uses the Sentai Rings to call on the powers of the preceding Super Sentai teams — and as a giant mecha. Each member forms their own colour-coded robot by combining the TegaSword with their signature "50"-series weapon and matching Sentai Ring. Tega Sword Yellow is Gozyu Tyranno's configuration, incorporating the Tyranno Hammer 50 and favouring a heavy hammer/melee style; the Wolf, Leon, Eagle and Unicorn counterparts of the other four members likewise form Tega Sword Red, Blue, Green and Black.

As a DX toy the item is made by Bandai (Japan). The DX Tega Sword was released on 15 February 2025, is built mainly from ABS plastic, and features electronic sounds triggered by a clap/pendulum sensor; placing a Sentai Ring on its head "completes" the corresponding robot. The Yellow configuration (Tega Sword Yellow) is achieved by combining the DX Tega Sword with the separately sold DX Tyranno Hammer 50 and the GozyuTyranno Sentai Ring. Related DX variants include the silver DX Universe Tega Sword and the limited DX Tega Sword Origin. Because "Gozyuger" received no Power Rangers adaptation, this mecha was never released as a Power Rangers toy — it is Japan-exclusive.
