It'd be sweet if we've flipped Powers by then and have Scarlet Maturity on call for the attack.
Scarlet Maturity would be pretty good for space combat, wouldn't he? Assuming he's able to pull his punches, his tactile telekinesis can easily deal with low gravity environments (say for example Elysium cutting power to a sector) and he can survive loss of life support too. Being a melee attacker, he doesn't worry about aiming shots to prevent breaching the walls and instead just has to move over to the schmucks to pummel them. His biggest barrier is whether the hallways are large enough for him to move in.
On the topic of preparing for Wider Than a Mile, I think it would be good to look into more esoteric powers for our P13s in addition to a frontliner. The last people to attack Elysium got infected with the very strange Jordano's disease which not even Zeno avoided and many people from the Horae Guard have weird powers (see Penitent Scholar's quantum bullshit, Seven's probability bullshit, and so on). Yara is likely a step in this direction, and assuming Cain gets a bruiser build I had some ideas for Homer that involve heavy abuse of delta samples.
Surreality
ΔZeno + ΔThe Giant Slayer + Crimson Soprano + Hydrocity + Daggermaw (Potency 13)
Assuming in the worst case that the delta samples discard everything but their synergies we have:
Keywords:
Space-Time Manipulation,
Transmutation, Flight, Solar Absorption, Energy Manipulation, Elemental Manipulation, Transformation, Enhanced Senses, Enhanced Strength
Keywords after known synergies:
Space-Time Manipulation,
Transmutation,
Fundamental Force Manipulation, Flight, Transformation, Enhanced Senses, Enhanced Strength
This is 3/5ths of the Reality Warping synergy revealed to us in Eidolon, missing just Biokinesis and Phasewalking. Daggermaw can be swapped out for some other 1 cost like Millions Minefield, though I wanted a spare transformation (RIP Multiplex) for the overall power I envision. The individual components are not that synergistic, but the 3 existing synergies taken together have a clear manifestation in my mind.
Entropy
bullshit manipulation!
In simple terms, entropy is a measure of chaos and disorder. In physics, the entropy of the world as a whole tends to increase (barring superpowers). It is the forward arrow of time that says an egg cannot be uncooked, that broken windows cannot be repaired without additional work, and so on.
So what if we had a power that could reverse that? To uncook the egg, unbreak the window. And to even refund the energy that went into doing those things and use them for something else. Defensively this may have some overlaps with what Arc or possibly Yara can do, though distinct from those we can intentionally turn the power in the other direction again to give it a very powerful offensive application. After all, the quickest way to increase disorder is to start wrecking things. In terms of destructive potential from harnessing entropy, something akin to New Dawn's Master of Disaster on steroids is what I'm seeing here.
Alternate pathway:
ΔZeno, ΔPrintemps, Epoxy (Potency 13)
Assuming in the worst case that the delta samples discard everything but their synergies we have:
Keywords:
Space-Time Manipulation,
Transmutation,
Fundamental Force Manipulation
Personally I would not prefer this version of the formula, as it requires extra research actions and doesn't save on delta sample costs. It assumes the delta sample and whatever the red research actions do won't take away Printemps' transmutation, which sounds reasonable. Epoxy fits in better with the combo than Crimson Soprano + Hydrocity I feel, but Printemps is a worse fit than Giant Slayer. And the first combo leaves space for a P1 transformation or energy manipulation as a nice cherry on top.
