Yo, hello to ya'll, I'm new here. I know the wiki for years but only decided to make an account now.
I wanted to ask, how familiar are you guys with the
Dungeon Defenders 2 crossover chainscaling Terraria to the
galaxy creation/destruction feat from the Old One in the first Dungeon Defenders?
This Reddit post talks about it and explains it better than I can.
Do you think it fits the
wiki's requirements for a canon crossover since the crossover is in both games (not onesided), part of the progression for both games (not non-canon), the verses being close to eachother's tiers (not an outlier), the worlds being connected with a portal, the crossover being acknowledged by the Dryad's dialogue and the Dryad being able to access her corruption form from DD2 with shimmer? I don't know if a verse page would need to be made for Dungeon Defenders before you could use these arguments on Terraria's page, but I think it should apply. Also, the Old One is literally Moon Lord's cousin design-wise.
You could make the argument that only Moon Lord, Dryad and the endgame Champion (and other characters comparable to endgame Champion) scale to it because the Dryad would chainscale to the cast from DD2 and she's canonically the only character that fought the Moon Lord besides the Champion alongside the other dryads. Meanwhile, she never canonically fought anything else since she is a support buff NPC (so you don't run into the problem of early/midgame scaling to galaxy level).
If you argue that Moon Lord doesn't scale because the Dryad fought him before the DD2 crossover and she is somehow currently stronger than the Moon Lord (which is dumb as hell, but I digress), you can argue that Post-Golem Champion and Post-Golem characters scale to it by the Champion defeating the full power Old One's army that directly comes from DD2 via the portal, which are comparable to the DD2 cast that are stronger than they were in DD when they fought the Old One. Pre-Golem characters wouldn't scale because they are clearly depicted as weaker than the Post-Golem Old One's army, which means that the Pre-Golem army wouldn't be at/using their full power.
This would also give more credibility to the universal Moon Lord statement from the lore alongside the nebula fragments description about containing the power of a galaxy and the solar fragment's about containing the fury of the universe, especially since all the dryads together couldn't truly defeat the Moon Lord.
