Gir

Gir is the awesome sidekick of Zim. He appears in some Mario stuff.

Birth
One day, Zim wanted a SIR, but his bosses didn't want to give him one, so they built a poorly built robot out of trash, thinking it would suck. However, they accidentally put in Awesome Comedic Power Packs in him!

Mario World
Gir, along with Zim, is a boss in Mario & Luigi: The False Adventure. They teach the bros. the Snack Basket move. During the fight, Gir will throw piggies, tacos, and cupcakes. Gir (like Zim) can only be hurt by Hammers, jumps, and the Snack Basket. Other special attacks will have no effect on him at all. Gir also appears in Waluigi's Mansion, where he can be found in multiple rooms eating pizza. He will offer some pizza to Waluigi for 50 coins. The pizza restores 50 HP to Waluigi.

Sonic World
Gir appears in Sonic Meets Zim and Mario, where he will sometimes dress up as a Sonic character. Gir will enlist the help of Sonic and Mario to find his Mini Girs. If they find them all and return them to Gir, he will reward them with a new move called the Dinner Blaster. Once the player collects all the Power Stars, Mario can blast to the top of Mt. Mobius, where Gir will reward him with 100 extra lives.
