Former ATLAS member Muon reunited with the boy group for a special showcase on 26 February, with fans rejoicing over his surprise appearance.
It has been close to three months since Muon officially left the XOXO Entertainment boy group, a move that caught many by surprise when it was first announced.
This time, he appeared with the group for the Sunsu Magic Comes Alive show that featured labelmates 4EVE, who were the presenters for the jelly brand.
The company later announced that ATLAS would be its new presenters for this year. In a further surprise for fans, it was revealed at Muon would be included as part of the campaign.
On social media, the hashtag #MuonATLAS trended briefly, as fans rejoiced and reminisced about the ‘OT7’ – the original seven members.
Muon stepped down at the end of 2025, but did not cite a reason for doing so.
