Luigi

Luigi is a major character in the TV show Mushroom Guard, and a member of the titular group.

Past Heroics
Prior to the start of the series, Luigi had helped Mario save Princess Peach from Bowser's clutches multiple times. Tales of the Mario Bros' heroics spread all over the world, including to Inkopolis, giving Zac and Sarah the inspiration to eventually move to the Mushroom Kingdom.

Peace with the Koopas
Eventually, Bowser and the Koopas decided it was time to consider a truce. A kart racing championship was held as a peace offering, and Luigi was one of the participants. After the championship ended, Bowser vowed to stop attacking the Mushroom Kingdom, a vow which would last for exactly 1 year before being broken...

Contemplating Retirement
When Dr. Hex threatens the Mushroom Kingdom, Mario pursues her with Luigi in tow. When the villain escapes, Luigi wonders if his glory days are over. He considers retiring, but Mario convinces him the time has come to train a new group of heroes.

Establishing the Mushroom Guard
When Zac and Sarah help the Mario Bros capture the newly emerged villain, Mario adds them to the newly-formed team, alongside Luigi, as well as old friends Daisy, Berry and Gold. Luigi plays various roles within the team: he transports them by piloting the Mushroom Guard Helicopter, he provides mission control for the rest of the group, he fights with his Poltergust, or he makes gadgets for the group, depending on the situation.

Personality and traits
Luigi's personality and traits are similar to his canon incarnation.

In general, although Luigi can be cowardly at times, he also has his moments of bravery, which are driven by the care he has for his allies.

While Mario prefers to rush headlong into battle, Luigi tends to take a more strategic approach, which proves to be beneficial in some situations, but detrimental in others.

This incarnation of Luigi is also quite adept with machinery, as he performs regular maintenance on the Poltergust and Mushroom Guard Helicopter, as well as making gadgets such as grappling hooks.

The relationship between Luigi and Daisy is left vague, however it is implied that they are dating.

Luigi gets along well with Berry and Gold, and he enjoys serving as a mentor to Zac and Sarah.

He shows respect to Princess Peach, and he views Toadette and Agent 3 as allies. Luigi is intrigued upon learning about Agent 3's heroics.

Enemies
Luigi has clashed with Bowser and the Koopa Troop for a long time. Prior to the start of the series, he was willing to give them a second chance, but when the Koopa Troop betray the Mushroom Kingdom, Luigi is noticeably disappointed.

Luigi is noticeably fearful of Dr. Hex and her magical abilities. He vows to protect the Kingdom from Hex's schemes.
