Considering glitch can assimilate DNA from the omnitrix and fuse it with tech unlocking new abilities. And vilgax's bioids have blank DNA and are linked to the omnitrix. What happens if glitch upgrades a bioid?
Okay, this is a very interesting question, I'm glad I got asked this:
Glitch, like any Mechamorph's ability, can fuse with tech to upgrade it using Mechamorph DNA. However, as said, Vilgax's bioids don't have DNA,
But for the upgrading to take place, we need Mechamorph DNA, not the DNA of the tech being possessed, as they don't have DNA. The bioids don't have DNA, but they are robots, so they are counted as tech, so we only need Glitch's DNA to fuse with the bioids to upgrade them, so even if they don't have any DNA, they are mechanical beings, and Glitch has mechamorph DNA, so that should be enough to upgrade the bioids. They can be upgraded the same way any Mechamorph could upgrade any tech. Even when they are related to the Omnitrix, they have no DNA, but they are robots, so if Glitch or any other Mechamorph took them over and fused with them, they could be given new abilities when upgraded using Mechamorph abilities.
