Xi Gundam/Penelope Ka Signature Exclusive Funnel Missile Set – What’s Included & Release Info

Bandai has just dropped some exciting news! The ROBOT Spirits (Ka signature) Ξ Gundam/Penelope Exclusive Funnel Missile Option Parts Set is officially coming to collectors later this year — and it’s packed with display potential for your Ka Signature lineup.

Release Date & Price

Here’s what we know so far:

• Release Date: August 2026
• Retail Price: $38 (US) on Premium Bandai’s US store
  (In Japan, it’s listed at ¥3,850 including tax, which roughly matches that US price.)

Pre-orders opened in early February 2026, so mark your calendars if you’re planning to add this to your collection!

What Is This Funnel Missile Set?

While the Ka Signature robot figures for Ξ (Xi) Gundam and Penelope are already major highlights for fans of Hathaway Flash, this exclusive funnel parts set takes things up a notch.

• This option pack includes funnel missiles and trajectory effect parts designed specifically for those Ka Signature figures — creating dynamic display setups that mimic the suits firing their psycho-guided funnel armaments.
• The set also comes with dedicated stands/attachment parts so you can position those funnels around Xi Gundam and Penelope just like in the movie’s epic battles.

Fan graphics circulating online also confirm that this set was teased alongside the Ka Signature releases, showing off how the mounted funnels will enhance poses and dioramas on display.

Why This Matters to Gundam Collectors

The Ka Signature line from Tamashii Nations is known for ultra-detailed figures with great poseability — and for Gundam fans, the Xi Gundam and Penelope are two of the most visually striking mobile suits from the Hathaway Flash film.

This funnel missile set isn’t just accessory fodder — it’s a dedicated enhancement that lets you:

✅ Recreate in-universe combat moments with psycho-control funnel spreads
✅ Add visual storytelling to your display shelf
✅ Make your figures stand out compared to static, non-dynamic poses

For model builders and figure collectors alike, that’s a big win.

Final Thoughts

Ξ Gundam/Penelope Funnel Missile Option Parts Set is shaping up to be one of the must-have accessories of 2026 for anyone following the Ka Signature releases. Whether you’ve already added Xi Gundam and Penelope to your collection, or you’re planning to pick them up, this set will help bring those suits to life with cinematic flare.

Stay tuned for pre-order restocks and regional release updates — and if you love detailed mecha setups, this one should definitely be on your wishlist!
