Lets talk Assist Trophies again. Who should become ATs? I feel like Rambi (DKC), Henry(FE), Garet (Golden Sun), Kamui (FE) and Cross (Xenoblade) should be ATs. Rambi because Animal buddy, Henry for dark magic, Garet because he's a side character, Kamui because dragon and Cross fights with a machinegun
Rambi by far makes the most sense for a DKC assist unless we want to go a bit more out there and have Cranky bounce around on his cane and toss death dentures at people.
For Fire Emlbem assists, Tiki is a far better choice for a Manakete and if we were going to have someone other then Lynn, I'd honestly suggest Micaiah to use some variants of light magic (which were excluded as a whole from Awakening).
Golden Sun... I feel like if Isaac becomes playable, it'd be more fair for someone from Dark Dawn (which I have yet to play) to appear. Possibly Matthew as Isaac's successor.
As I kinda doubt XCX is going to get a second fighter because nobody is that innovate from what I've seen of the game, Elma as a face for the game seems better for an assist.
I'd love to see Slippy as a "Joke" assist who kinda just flails about and occasionally drops things like Smart Bombs or Motion Sensor Bombs.
Hades as a Resetti style assist that just takes up a chunk of the screen with dialogue would be amazing.
Eggman/Dr. Robotnik using his flail of death from Green Hill Zone seems like a great choice for a Sonic assist.
Beyond that, I can't really think of much besides pulling out random retros or crafting something for Rhythm Heaven.
