Red Core Medals have bird powers; yellow Core Medals have big cat powers; green Core Medals have insect powers; silver Core Medals have heavy mammal powers; blue Core Medals have marine animal powers; purple Core Medals have dinosaur powers; and orange Core Medals have reptilian powers. There are 70 Core Medals total from the series, each three from a Greeed divided in three groupings for the use of OOO: Head, Arms (Torso), and Legs.

In Tajadol Combo, the Taka Head becomes the Taka Head Brave (タカヘッド・ブレイブ Taka Heddo Bureibu). It was the first Core Medal to be seen in the series. After Ankh's sacrifice, only one of these remained before it broke into two halves while the last intact copy was sucked into a black hole. Following the loss of all the other Core Medals to the black hole, this is the only Core Medal to still exist in some form in present day, the broken halves taken by Eiji on his travels. After Super Hero Taisen, Eiji now has the sole remaining Taka Medal, but he still needs to get Ankh's broken Core restored. When changing into Combos, the name would take the first kana for main Combos and the entire name for Random Combos.
