Millipede is an Eoarthropleura. He was Dr. Cockroach's seventh Creature, and his fifth regular creature.
His card, along with the Move Cards Earth Barrier and Earthquake, winded up in Gabon. He was activated when some playing kids kicked open the Card Capsule. He battled Thylaco, and nearly won, but lost in the end when Susan came up with a clever strategy. His capture removed Iguano and the Anurognathus Dozen from the team. He was later revealed to be a 5 on the Power Scale. Thirteen episodes later, he battled in a battle royale, but was defeated. Two episodes later, he battled in another battle royale, but was defeated. Four episodes later, he was removed from the team by Sid's capture.
The first copy of the Earth Barrier Move Card was in his Card Capsule, and was activated along with him.
The first copy of the Earthquake Move Card was in his Card Capsule, and was activated along with him.
He has never won a battle.
