xander_(student_swimmer)_(fire_emblem)
Tag used for Xander (Fire Emblem) from Fire Emblem, specifically when dressed in his summer attire from the Fire Emblem Heroes 2017 Nohrian Summer banner.
Can typically be identified thanks to the attire's characteristics: black swim trunks bearing the Nohrian crest.
May feature his weapon: a floatie shaped like Lilith (Fire Emblem) in dragon form.
The design of this outfit is identical to the swimsuit Xander wore in Fire Emblem Fates’ Beach Brawl DLC. The Lilith-shaped floatie is also from that DLC.
Note that it's possible (especially for older artwork), to depict Xander in a swimsuit without it being the one described above, in which case this tag should not be used.
