October

October is the first new Jabber Ball we see in Otamatone vs Jabber Ball 4: Dimensions. He is known to be a helper of the universe to make sure things stay in order and don't collapse. He is essentially a god due to his power. He usually glows a neon orange when he's at his full power.

In his first appearance, Otamatone vs Jabber Ball 4: Dimensions, at first, October seems like a threat to May and her quest to restore all life in her dimension. After many different events, May gets attacked by Dr. Otas. The one who saves her was October. Initially, October tried to kill May because he didn't understand what she was gonna do to the dimensions. He thought that she would cause problems and destroy the timeline of each universe she went to. Eventually he learns her motive to restore her planet, so he sides with her. October teaches May how to travel through dimensions with the Dimension Gem, which he possesses.
