Marabounta (monster)
From Code Lyoko Wiki
The Marabounta is a monster created by Jeremie, based on the principle of ants, that if working together, each on individual tasks, collectively they could accomplish tasks worthy of one or more intelligent individuals. They only made an appearance in the episode Marabounta. It existed as a black blob that started out as a single sphere. The single sphere quickly multiplies and becomes a black ooze. Its purpose was to get rid of XANA's monsters, like Crabs, by engulfing them, thereby allowing Team Lyoko to achieve victory much easier. Its usefulness was rendered null, however, when it sensed the link that Aelita had to the Supercomputer, and was eliminated through a never-before-seen gung-ho collaboration between the Lyoko Warriors and XANA's monsters. It was destroyed by a modified lazer arrow, armed with a virus, that struck the original sphere.
Yumi was the only one of the Lyoko Warriors who was coverd and devirtualized by the Marabounta
