Hero Relationships Puzzle

I decided to amuse myself by creating a diagram of the major relationships between SotM heroes.  Unfortunately, it appears I forgot* to label the diagram!  Can anybody help me out?

I have included every hero in Sentinels of the Multiverse, including OblivAeon, but have ignored Sentinels: Tactics.  And this is individual by character, not by hero.

I obviously couldn't include every relation, so this draws primarily on relations mentioned in various bios.  Not all of them are, though.

This forum lacks decent spoiler tags, so if you could post answers in white so that they cannot be read accidentally, it would be much appreciated.

*For various definitions of "forgot"

This was very fun, thanks for putting it together! I'm pretty inconsistent with hero name vs real name so I hope it's all understandable. I'm not so good with the white text, so I've linked my answers to a Google Doc, which I hope works. 

How did I do?

I'll have to double check once I'm no longer on my phone, but I think that you got all but four correct, in two pairs of swaps. For one pair, you should double check recent variant bios. For the other, pay more attention to the line colors.

Edit:  Yes, all but four are correct.  I'd tell you which four, but it would make correcting them trivally easy.  

I'll see if I can revisit it soon. Unfortunately, I'm color blind (not completely, but enough,) so differntiating based on that is difficult. 

That had not occured to me.  Here is a new and improved version, for those with color-insensitve eyes.

Thank you! That's much clearer. Considering that new information it is obvious that 35 and 37 are switched. I also see that I had the wrong connection with 9 so I imagine that is one of the incorrect pairs. It would make sense for the person I thought was 9 to be 21 in connection with 7, but I don't know why the person I thought was 21 would be connected to 12. A line in the bio suggests that 9 and 25 may be switched, but 25 has solid connections where he/she is and I don't know why 9 would be connected to 28 and 19. 

So I suppose I'll guess that 35 and 37 should be switched as well as 9 and 21.

You are correct!  

When I saw this thread title, I thought we'd have to explain how Young Legacy is her own grandpa.

There's an awful lot of cards that involve Guise being with Unity (mostly from Villains of the Multiverse decks). I'm beginning to wonder if Guise/Unity are a couple, or at least that Guise has a crush on her (or vice versa)?

I'm guessing they just play off each other well and make good partners. That's just me, though. 

They're also two of the heroes who seem to get taken less seriously than others.  In Guise's case it makes sense but for Unity the whole Intern label seems to be her hurdle.  

Yeah, Iron Legacy's speech to regular Unity in lead position in the video game is probably the meanest thing he says, but I also think Unity has the best comeback to him as well. Yet it also seems like other heroes treat Unity less as an almost 20 year old and more as a tween, but that might have to do with how she treats her golems.
