Phase

Whenever there's a faint blue glow, or some faint robotic chirping, that's a hint that phase is nearby.

He may seem young, but if looked closely, he'll start to appear like he came from a million years ago! Oddly enough, he is indeed from an old research facility.

Personality
Although unable to directly speak, he does chirp when lost. That chirping translates to "Help!", which has been known to be the only chirp pattern he knows, and is used the same way as how a young bird would cry for help.

What birds find funny, is that he's like "an Under-the-radar Attention-seeking missle". He pretty much finds comfort when with someone, and would even try to play with other young birds, like Pyro or Luca.

Once he's alone, he starts thinking beyond reality. He starts wondering if someone's watching him beyond a screen, waiting until he makes a move. He starts getting afraid, as to why the thought came to mind, and flees to safety! Wait... THIS IS BEYOND A SCREEN!

Ability
Whenever spooked, he'll start defending himself uncontrollably with a built in 3-burst laser. This does heavy damage per shot, and can wreck up to a tough stone block. This attack, like Corporal pig's attack, is wasted when used on ice and stone blocks, so it has to be aimed just right.

Just like Unknown, his weapon can handle nearly any situation, and is aimed, but can only be used once.

Backstory
At some research lab, some birds were testing some machines. Some were automated fridges. Others were defense systems. Heck, one of them was a toaster! Then... one test mech caught the eye of a specific bunting. "That's... That's not even allowed in society!" She says, angered. "Grrr... That thing's gonna have to go! WHAT WERE YOU DODOS THINKING?"

Another bird rushes in, panicked. "You said that to a paintbrush we were working on!" He replies. "Dang it, Holding onto such an oversized art tool mocks me!" The bunting responds. "And now you're taking down the rest of us with that thing? IT'LL END US ALL!"

She looks at the mechanical Tanager, and enters the test cell. A pig then says "Uhh... She's gone mad, hasn't she?" The Grenadier responds with "Well, I can tell you that if she had a grandson, he'd be the only welder of a paintbrush."

"Dang it... I have to take this DOWN!" The bunting says, insanely.

Suddenly, the mechanical bird's eyes start faintly glowing, with the rest of it slowly moving, like it's coming alive after being struck by purple lightning. "What!?" She responds as the machine awakens.

Once it fully awakens, it looks at the mentioned bunting, and gets close to her. The bunting backs up a bit, scared. The machine just procedes to cuddle with her, showing that he's friendly, and means no harm.

After a week, they observed his battle abilities, after one brave bird dubbed him "Phase", named after his hidden weapon, the Phase blaster.

Once given a target, Phase immediately gets scared by the terribly drawn pig target. "...Am I that hideous?" The pig reacts. The other birds trade looks with eachother, and agree that phase is utterly useless.

With that in mind, Phase is put away into a dumpster, and barely gets heard of again... or so they think.

an unknown amount of years later, something re-activates Phase, realizing that the dumpster has never been used. Phase, suddenly spooked, looks around and Sees a moss covered city, with a larger city in the distance. He runs there curiously, as to why there's a huge city.
