Honestly I'm in the same boat. Quite frankly the only thing he's missing is an amiibo.
Considering just how often he was billed as
the main character of the three Awakening protagonists (the mainest main?), which is also the Fire Emblem game that's gotten the most steady and apparent international marketing. Add to that all of his appearances in crossovers with Lucina (appearing in Monster Hunter as costumes, appearing in Project X Zone 2 as a duo, etc), or without her (#FE), and also factoring in the fact that he's one of the few Fire Emblem characters with physical merchandise (mainly his Nendoroid to go alongside Lucina's figma), and he's almost Nintendo's go-to Fire Emblem guy which is, again, saying something for a character that lacks an amiibo (the reason the other non-Lucina Smash FE characters make guest appearances in the first place).
That's just the way I see it anyway. At the very least I'd say he's honorable mention.
