GMVT-02 Gundam Yesterday

GMVT-02 Yesterday (General Machine Variable Tactics Configuration Zero-Two), simply called the Gundam Yesterday or the Gundam by the crew of the Golden Child, is the combined form of the XZF-04 Youngswallow and the XS-YUNINN-02 YUnWEI II.

It is the titular mobile suit of Mobile Suit Gundam Y, co-piloted by Aldrich Reno in the Youngswallow and Musashi in the YUnWEI II.

Characteristics
Whilst the Youngswallow, despite its ambiguous origins, and the YUnWEI II, an extremely advanced newly-produced mobile suit, perform admirably by their lonesome, docking the Youngswallow onto the YUnWEI II functions to removing the mobile suit's various limiters, granting it capability to rival even the Jovian Interceptors' mobile suits in speed and response time.

Aside from this, however, the pilots of the Gundam Yesterday is also then granted access to its experimental internal system, the "Graviton Accelerator"...
