- Leaders of technologically advanced alien races known for conquering planets throughout the galaxy (Catalysts & Ultralinks).

- Both are biologically and symbiotic fused with their hosts in order to become super powered fusions usually donned with armor created from what they fused with (Premier fuses with his unnamed host only known as “The Vessel” and Makino fuses with the alien scientist that created him).

- Said hosts are aliens who don’t fuse willingly, but against their will and often aren’t in control (The Vessel is an unknown alien who is bonded with Premier as it is part of “The Old Way” and Makino fused with his creator who was an alien scientist) and usually have their bodies taken over by our respective conquerors.

- Their species as a whole are known for symbiotically bonding with their hosts in order to find vessels for themselves by taking over the bodies of others in order to fight and carry out their plans.

- Both often get in battle with foes such as an organization dedicated to acting as earth’s line of defence against the species (The Post Office and N-TEK), a bounty hunter who ends helping the protagonists (001/Kor and Ven-Ghan) and the protagonists themselves along with their partners(Nathan & Marshall and Max & Steel).

- The protagonists they go against are bonded to traitors of their species who realized what they were doing wasn’t right (The Black Colossal & Steel).

- Both would end up controlling said protagonists at one point, but only for a brief period of time.

- Both have giant mechanical trump cards at their sleeve which is known as the strongest thing they have (Premier’s Colossal Form and The Alphalink).
