Despite being the successor of the Phoenix Gundam, the Halphas Gundam is considered to be inferior to it in specs due to its lack of Nano-Skin Capabilities and the Black Box Replication system. But the mobile suit itself is considered a step up to its predecessor by incorporating a set of cross-like wing binders which serves as both boosters and it's main long ranged weapons system.

The Halphas Gundam's wings are actually four powerful mega beam cannons. It is also armed with a beam rifle as well. Other weapons include vulcan guns, beam sabers and a couple of funnels stored on its wing binders. Finally, Halphas Gundam can transform into "bird mode" and perform a special attack called Burning Flare by covering itself with super heated energy released from the binders it then rams through several targets with high speed. While Halphas Gundam can only transform when performing the Burning Flare, it is flight capable even in its MS mode.
