Winged Guardian "Sentinel"

I once saw an episode of an anime called "Bakugan". One of them was called Altair and I really liked the look of it. Sentinel was inspired by Altair.
Controlled by a sophisticated AI, Sentinel can use three types of attacks.
1) The "Odem" high yield focussed plasma beam cannon, hidden in its maw. This weapon can create temperatures that make the surface of the sun seem cool.
2) The Vortex attack uses the G-diffusors in Sentinel's wings to create a localized, rotating gravity field that spins a target around at extreme speed. This attack is designed to confuse and incapacitate people rather than causing harm to machinery.
3) The feedback attack is Sentinel's most powerful ability. Every time it is hit by an energy-based attack, it will absorb a certain amount of this attack's energy. Once its storage batteries are full, it can release this energy in one powerful burst. This attack can "tune" to an enemy's energy signature and become stronger each time it is used against said enemy.
