Kupo Power Wattson

Lilytix​ Sadly, its possible that it won't come back to the in-game store since it was part of the Final Fantasy event, (but here's hoping that it does!)

Wattson's Kupo Power skin, (for reference):

There's also a new Wattson skin called "Apex Icon", it is a Mythic prestige skin, but if you have the Heirloom Shards, you could pick it up after the event for it ends in 6 days:

Wattson Skin | Apex Icon

Wattson Skydive | Shooting Star

Wattson Finisher | Dance Dance Electrocution
