Headcanon #1: He can move by himself because of his human spirit (Sean) Possessing him.
Headcanon #2: Sebastian/Voltron never told Bumblebee and his team, his name when he crashed on Earth but he told them to just call him Volt.
Headcanon #3: He wasn't able to talk with his unmovable face so he used signs to communicate with others until he formed a new movable face.
Headcanon #4: He is actually taller than Grimlock as it was shown when he was next to Big Ben in London but he has the ability to shrink and enlarge himself (Just like the Meggies)
Headcanon #5: He covered his face when his unmovable face came off as to not show Bumblebee his movable face until it was fully formed.
Headcanon #6: He was the first person to ever get befriended by Bumblebee.
