Yeah, their super bad ass brothers. So would a robotic planet be like their cousin?

One planet transformer is enough imo.

I think adding more artworks would be a good idea, but only if it's mostly for dysons since they pretty much all look alike just with different colours. Metallics already have several different artworks for them.

Each planet has 5 planet artworks, Aphotic nearly has 2 Identical Artworks, that Dan should work on the look-a-likes and change them into something unique.

One per player that it's best used on a crappy planet, as a pose to building a planet up to 22x yourself.

Ok, first off, Red/Blue Giants, are stars, not planets, and even the Largest planets in the universe, are Dwarfed in comparison to a Red/Blue Giant.
Second, your ships shields and defenses would be more than powerful enough to protect you from some magma from magma planets. I mean, weapons like Quasi-chaos blasters or Thetachron cannons (if you believe the descriptions in the research tree) are WAAAY more powerful than a bit of magma, and your shields withstand several hits from those. The magma would offer little to no help. hell, with proper shielding, you could fly your ship directly into the magma, and land under"water".
And a small add on to that, you dont actually land on the planets, you attack them from orbit, or flying around inside the atmosphere. magma, (which on a magma planet, would be on the surface) wouldnt have any effect on a ship in orbit.
[Edit]
I see now you said Invasion Defense. I guess thats right, 'cause i imagine you'd have to land troops to invade the thing.
Maybe add a chance of loosing some crew when invading a Magma planet? From falling into magma pits and such. Tac officers, Helmsmen ETC.
Now i know how much you guys all hate loosing crew, so you could add something to make up for the loss, like an invasion success effect.
Third, turning a planet into a black hole, would make it smaller, not bigger.
(black holes are un-imaginable amounts of matter compressed into such a small field that it tears trough the fabric of space itself)
For example, if the matter of the entire planet Earth, were to form a black hole, that black hole, would only be about the size of a marble.
Not to mention of course, that turning a planet into a black hole, would destroy the planet entirely, so it wouldnt add anything to production, i anything, it would remove all of it.

And also, your punctuation is terrible. I know thats not relevant or important, but im a stickler for details. Sorry.

But anyway, you are right, its not hard to come up with some fancy planet upgrades, the hard part is making it viable to the game, not under- or overpowered, something that adds an interesting new element, and is realistic according to the laws of physics.
It's all in the details.

Also, it boggles me that Dan has never added Asteroids... It's been suggested so many times, and so many different suggestions for what to use them for.. They should be fairly easy to code, and it would add A LOT to the game, both for newcomers, and the senior players if done right.
Just sitting here thinking about it, im getting Idea after Idea after Idea about how to encounter them, what they could do, what they could contain, what could happen when you finish them...
I'm telling you, Asteroids are an untapped Gold mine/Oil well, just sitting there, waiting to be opened.
Dan, if you need Suggestions for what to do with Asteroids, or a lot of other things that Should be added to the game, you've got my Email address.
But i digress...
Thoughts? Ideas? Suggestions? slaughtering comments?

How about energy?

never gonna happen as Dan is against people ranking up quickly
