Aka's race is the race both Abo and Cado, two brothers who were former elite soldiers of Frieza who once ranked with the notorious Ginyu Force, are part of. They appear to be humanoids with an onion-like roundish shape head and very roundish body structure and shares some appearance similarities with Dodoria's race (especially after Fusion)
Members of this race possess the ability to merge with each other, and to create even stronger beings, as seen in the case of Aka who himself was strong enough to handle base Goten and Trunks (who had easily defeated Abo and Kado) and survived Super Saiyan Gotenks' attack, only to be easily defeated by Super Saiyan Goku. They were the ones to execute the Attack on Gure's planet.
There seems to be many others of this race amongst Frieza's army (who served also under Sorbet's rule) as in Dragon Ball Z: Resurrection ‘F’ there are soldiers who seems to be part of this race as well among the 1000 soldiers the tyrant brought to Earth with him, where they're defeated by the Dragon Team and Jaco.
