Glowworm is a strange glowing mammal and Matt's pet. He has black and white fur and blue-green eyes.
He is a kind, lovable, and intelligent animal. Ever since he was saved, Glowworm loves Matt dearly and is heartbroken when he sees him sad. He clearly isn't fond of other Sky Knights. He is also very loving towards all his animal friends.
Glowworm has the unique ability of glowing but only when his tail is wrapped around an energy source, such as a flashlight or a lamp.
Trivia:
Though not a worm, Glowworm is named after his glowing fur and long worm-like tail.
