Ulala is often portrayed as confident; often heading into danger without showing the slight trace of fear. When the Morolians invaded Spaceport 9 and people fled in panic, Ulala confidently strutted forward to deliver her report. In Space Channel 5, she often remarks smugly about her performance if she does well against her opponent; stating "That was fabulous!" or "I kicked butt!" with a confident tone. However, Ulala can get less smug when she doesn't do well; stating phrases like "I...saved SOME of them, at least!" and "I gotta get better at this.".

In Part 2, Ulala seems to have taken a less confident stance against the Rhythm Rogues. She often exclaims shock at some of the drama in the game, such as when people are taken hostage. In the original, she stated these developments calmly and professionally. However, Ulala still retains plenty of her confidence from the prequel, stating during the first boss fight "Whatever happens...I'll give it a dance!".
