As I stated earlier I have an idea for an android protagonist. But playing an android has a major flaw, I have a solution for it that I want to run by everyone before I go nuts with it.  
Androids don't grow stronger like the biologicals does. As such you pretty much have to either start at a higher power level and eventually become obsolete, or you find some way of getting stronger that makes sense.

DBZ gives us two examples of the latter. Either by absorbing energy (which worked really well for Gero and 19) or fusing with other androids like cell.
After thinking about the fusion-thingy I got my idea.


Lore: Dr Gero wasn’t the only android-builder in the old red ribbon army. There was at least one more with a vision matching Gero’s, but in a totally different way. Gero built a small number of increasingly powerful androids, the strongest able to stand up even to a super saiyan. The other, called Dr Wheir, instead focused on massive-scale production. He built many factories around the world in secret and had them producing hundreds if not thousands each of the same android. This model had something that Gero would later steal for his cell-design, the power of fusion. Each model was extremely cheap to build, but didn’t hold much power on its own, but by harnessing the power modules from each other they could grow in strength by about 30% per module. 
Dr Wheir built an army able to conquer the world, one that would grow more powerful with each loss, instead of weaker. Yet history doesn’t remember his name. The red ribbon army was destroyed only minutes before the androids could be unleashed, Wheir was driven away from his lab and killed by bandits before he could tell anyone about his army. 

Long after the death of Goku (the final one) an adventurer stumbled into the ruins of one of Dr Wheir’s factories. Looking for a terminal with information about the place the adventurer accidentally activated the production line and a single android was engaged. The old hardware had deteriorated though, and the last software update became corrupted. When the android booted up it found that it had a similar programming as 17 and 18, but the insubordination software that normally would stop an android from disobeying its master was damaged. This android had perfect free will, not disobeying orders out of choice but because they were not needed. 

Mechanics:
There are a number of androids all over the world, the combined power of each would give the last android a power level equal to a super saiyan god, but it is unknown how many androids are actually operational. 
The android has activated a beacon that will draw all of the working androids to it, but the rate they will do this varies a lot depending on what kinds of obstacles they will have to clear before uniting with their dominant brother. There is also an algorithm in place to spread out the load of androids to the different factories, so even though there are working androids close by, the algorithm might decide to send one from the other end of the world instead. (in short, the android will not simply go “hey, I need more power” and suddenly fifteen powerups appear. That’s just bad writing)
In the beginning the androids are so similar in power that they can stay and fight, but later they will pretty much become powerups. 
When a power module is removed this will automatically trigger the self-destruct sequence. Careful timing and planning can therefore result in a powerful explosion (attack) that also powers up the android. 

Thoughts?
