The robots who like Robotack and the others come from Harappa (ハラッパ国 Harappa Koku?) and live like humans. The elite robots of Harappa kingdom can transform into Special Mode (スペシャルモード Supesharu Mōdo?) from Normal Mode (ノーマルモード Nōmaru Mōdo?) by the Magnet Change (ジシャックチェンジ Jishakku Chenji?). They are based on legends or myths, with some ending their sentences with onomatopoeic sound representations of the animals they are modeled after.
