Athena & Robikerottsu (アテナ&ロビケロッツ, "Athena and Robocarrots") was a Hello! Project unit consisting of Niigaki Risa, Mitsui Aika, Nakajima Saki, and Okai Chisato.
This unit was formed in 2007 for the anime Robby and Kerobby, in which Niigaki voices a character.
In this group's original line up Tsuji Nozomi was supposed to be leader, but because of her maternity leave, Niigaki Risa joined the group instead.
The group disbanded in 2008.
