Considering Luka's usual attitude, Wonder-Pink shows considerable patience with him. Considering how she usually handles the antics of her fellow team-mates (particularly Wonder-Blue's posturing and Wonder-Green's flirting), it's quite unexpected.
In one chapter, Commander Nelson mentions that Wonder-Red had once said that as important as his mission to save the world is, his civilian profession as a teacher is just as important.
This particular discussion is what marks Wonder-Blue's full transition from his I Work Alone mentality and his doubt of Wonder-Red's leadership, and his pledge of support to the Rookie Red Ranger.
During the final battle (well, one phase of it anyway), Vorkken's ship, the Meizerr returns, when it was thought to have been destroyed a couple of chapters back. Vorkken opts to jump aboard and support the Wonderful 100 from there. When he does, Chewgi, who had defected from Vorkken's band, interjects:
Chewgi: We're coming with you, Vorkken.
Vorkken: What...? Good to have you back, Chewgi.
As you unlock secret characters like Chewgi and Luka, they show up at the head of the pack when you start a mission.
The message that appears after beating the epilogue on 101% Hard:
Your face will be forever masked. Your tomb will be forever unknown. You are truly a wonderful one.
