The Kobalts are a solid blue team introduced in MarbleLympics 2016. After earning 2 silver medals, they finished in 9th place in MarbleLympics 2016. However, Kobalts tied for 13th in the MarbleLympics 2017 Qualification round and were unable to qualify. They also did not qualify for the MarbleLympics 2018 after finishing 5th in their qualification group.
The Kobalts and the Rojo Rollers share the sad distinction of being the only two teams from the first MarbleLympics to have yet to appear in any other edition.
The badge for the Kobalts includes 26 white dots on the rings surrounding the dark blue inner circle. These white dots represent the electrons of the cobalt element (Co).
That said, the badge should actually include a 27th electron in order for the cobalt atom to be balanced. The badge instead represents a cobalt cation, or a positively charged cobalt ion. The designer of the badge, Tim Ritz, states that the extra electron was omitted in order to make room for the "JMR" lettering that appears in every other ML team badge.
