Jay Guthrie/Sooraya Qadir
Roberto Da Costa/Amara Aquila
Trevor Hawkins/Lin Li
Rico/Ziggy
It’s a shame Icarus/Dust will never happen cause Jay is dead.
Magma/Sunspot almost happened once. In New Mutants Vol 3 #50 they kiss and it may have been implied they got together but then Roberto to the Avengers. Separated them and neither are with anyone currently but will they ever officially get together?
Nature Girl/Eye Boy are not used enough and sadly I don’t think will ever be more than wallpaper. Same for Rico/Ziggy.
Sadly I doubt any of these will ever sail!
