Glaive

Kidnapped at Bubbles' birth, he escaped when his younger brother hit 7. He may have been changed into a firey Psuedo-Demon, but all that just made his firey personality more extreme, extreme enough that it became a weapon!

Appearance
He looks identical to bubbles, save for the face, iridescent-style fire feathers, head spikes, eyes, and size.

When enraged, his eyes start glowing light blue, along with his mouth glowing a magma-like orangey-white.

Ability
His ability is a combination of Sonic's and Pyro's abilities, which lets him roll into a spiky fireball that bounces off of blocks like stone, while piercing through blocks like wood and ice.

He is recommended in situations where pig defenses are extremely tight with wood, with very few stone blocks. His ability to bounce off of stone and Tougher blocks gets a bit annoying, and is reccomended to aim him in the right spot.

Backstory
Back in the day, 5 years before bubbles was born, Glaive was goofing off, eating candy, and being his usual self. He was a rather crazy bird back then, so why would he want to give all that up?

5 years later, he was shocked to see that he was about to get a brother.

"So, I guess I'm having a brother then?" He asks. "Yes dear. I did just had a situation with that bird, remember?" His mother answers. "Oh... right. He said that he wanted a son named 'Bubbles'." He replied.

Later that night, he was fast asleep, dreaming of being with what he thinks his brother would look like. However, a pig was spying on him, chanting about "mutant birds". When the insolent swine got the chance, he slammed the young bird's face with a frying pan, and kidnapped him.

His mother woke up from the slam.

"No... NOT MY SON!" She exclaimed, noticing that her first child had been taken by the pigs.

5 MORE years later, he wakes up in some odd green fluid.

He struggles to talk.

"Ugh... brotha... what year is it?" He manages to say. "2016" A pig says. The pig was small. Adorable, but is as smart as he is stubby.

"Wha? I was... gone fer... 5... years? He responds. "Yeah! Heh-heh! Your mutation is almost complete! After a few tweaks, you'll be the biggest threat to birdkind!" The pig says, with each word sounding more intimidating than the last. "Wha... in the heck?" He reacts. "You're... you're turning me... into... a demon?"

"Uhhh..." the pig says, as padalin birds come crashing in. "Ok, regroup! We got a pig trying to create a demon" The padalin leader says. "I... am not... a DEMON!" He exclaims. Soon, Glaive starts spinning at a slow pace, but starts spinning faster every second. After 20 seconds, the liquid turns red, with the glass cracking. Soon, it breaks into shards!

"I am not a demon!" Glaive exclaims. "I am a normal bird, just like the rest of you!" His appearance betrays his statement, since he's on fire, has spikes on his head, and has demonic eyes. "We don't believe you. ATTACK!" A padalin says.

After escaping to a beach, Glaive pants after spinning his way there. After recovering, he sees a nest, in which has bubbles, eating candy.

"Bro? Is that you?" He says. "AGH! DEMON!" Bubbles exclaims. Suddenly, bubbles slowly realizes that Glaive called him "bro", and then quickly rushes to hug him. "I forgot that mom mentioned you" bubbles says. "I'm sorry if I mistook you for an underworld being""Everyone does that to me" Glaive responds.

"So... You look like a Glaive..." Bubbles says. "Mind if I call you that?" "Sure, since it suits me!" Glaive responds.

Today, he looks out after Bubbles, camps out with Hal and Pyro, and has little conversations with Unknown. He's gotten into the name game, giving names to the nameless, and destroying most pigs, along with the idea that makes others think that he's a demon.

Trivia

 * His eyes are strikingly similar to Midna's, and Violet's chaotic eye.
 * He could be based off of Diablo, but he's actually based off of another idea, which is a dragon of the same name that popped up in his creator's head.
 * He is the most mature, and the most sane of the flock. Despite this, he's a candyholic.
 * He's an excellent example of the Metaphorically speaking TV trope, as the Padalins believe he's a Demon. He looks the part, although he's just another mutant.
 * In fact, some may think of him as a pheonix. Again, he looks the part.
