Since the Earth Union made first contact with the Mekkari, endless new discoveries about the biotechnology and cultural capabilities of this species have been achieved without problems thanks to the fact that the Mekkari are not hostile to other species.

However, although they are always discreet and do not want to talk about the subject, there are rumors that before their formal contact with the other civilizations of the galaxy and even now the Mekkari assimilate other beings to their species if they came to their world by mistake and were seriously injured.

This is because some Mekkari seen have physical characteristics combined with those of human beings, Zoosapiens, Garlesh and Xerenet, beyond the fact that sentient robots simply try to replicate characteristics of the other species they have seen and test them on themselves, that idea is ruled out when it is seen that these "hybrid" Mekkari are capable of speaking the languages of their respective characteristic species without any problem or having to do a mental scan as if others do, in addition to occasionally showing more emotions when interacting. with other biological beings, but they do not seem to present memories or anecdotes of who they were before being Mekkari if they were really assimilated.

The best known case is that of Arvask, a Mekkari with canine characteristics and capable of speaking without problems English, Spanish and Cransov, the language of the rural population of Janus, giving clear indications that in the past he was some Zoosapien pilot who went to give to Vistran never to return, who met the vigilante Pulse when he traveled to the planet in his first days of contact with the Terrestrial Union looking for an Aspid target, meeting the species thanks to Arvask, one of the only intermediaries between both civilizations as to be a Security Guardian of the environmental reserve zones of the planet

Arvask is an agile and precise warrior, with great use of bladed weapons as well as the light cannons composed of Kestyern glass used by the Mekkari sentinels, and with the animal characteristics of a canine zoosapien, he can interact without difficulties in natural environments and handle another class of machinery outside of his species, and unlike the other identified hybrid Mekkari he does seem to have slight glimpses of who he once was before being converted into a biomechanical android, being a great ally for the new group of Pulse defenders and to intercede between the communication of the Mekkari and the Earth Union.
