-Mentors to a young main character (Johnny in Gyro's case, and Simon in Kamina's).

-Both of them were the reason the main character went into an adventure.

-Even though they are the mentor, they sometimes learn things from their pupils.

-Both possess spiral-themed abilities (Spiral Power for Kamina, and the Spin for Gyro)

-Even though they're the oldest heroes in their story, they can be quite childish at times.

-Both died very young during the penultimate battles against the enemy forces (Kamina died just as the Dai-Gurren Brigade was about reach Teppelin, and Gyro died during the fight against Funny Valentine).

-Their deaths were very influential for their pupils, and it helped them learn more abour themselves and their powers.

- They're both husbando material
