However, he does usually express his determination and belief in the power of the dragon when it appears:
* "Come forth, Stardust Dragon!" (This is more a general summoning phrase.)
* "I believe in you, Stardust Dragon!"
* "With you by my side, I can do anything!"
It's important to note that Yusei's relationship with Stardust Dragon is deeply personal, and he often shows trust and confidence in its abilities, rather than using specific catchphrases.
