You know an alien is special when I dont give him the green background (plus he blended with the green too much), here is one of the most powerful aliens in the Omnitrix, the galactic inferno NOVABLAZE!!!

Novablaze is the Omnitrixs DNA sample of a rare Drazukian, which are born in supernovas.

Abilities

• Nebula Physiology - Novablaze is a huge cloud of fiery nebula originating from a meteor within himself. Usually taking the form of a giant bird like creature, but is ultimately a shapeless form of gas and cosmic fire.
• Cosmic Fire Manipulation - He can project and manipulate large amounts of fire and cosmic energy, initiating purely destructive forces.
• Interstellar Travel - He can fly at incredible speeds, achieving hyper speed within a vacuum to travel across solar systems.
• Size Manipulation - He can expand and shrink the amount of nebula he has to change his size. Such as growing to the size of a moon and even condensing all of his nebula into his flooring meteor to fit into small spaces.

Weaknesses

• Massless - Whilst he is incredibly powerful, the only real mass he has is his meteor. His fire blasts can knock back enemies, but he doesnt have any form of strength to hold things.
• Suction - Large vacuums can absorb his fire, leaving him as just a meteor. It takes a minute or two to generate his nebula form again.
