37

Dr. Hikari researches the Crests of Duo and discovers that those marked with it have higher synchro-ratings, meaning CrossFusion is more possible with them. Meanwhile, Yai is planning a fireworks party, so she urges Lan to bring Fyrefox and Mr. Match to help with the festivities. However, BlizzardMan and CloudMan attack with orders to delete MegaMan, and they transform the hall into a raging blizzard. Lan, Dex, Mr. Match, Dingo, and Fyrefox all team up to overcome the Darkloids, and Fyrefox is able to delete BlizzardMan in the real world using a firework dispenser. Fyrefox thus receives the Crest of Duo. (Source: Wikipedia)
