Giblet

History
Giblet is a time-displaced Saiyan from ancient times and the brother of Shallot. Not much is known about his past, aside from the fact that he was quite evil and antagonizes Shallot repeatedly, not unlike Raditz did to his brother Goku. At some point, Giblet gained the ability to transform into a Super Saiyan.

Meeting Cell and Kermit
In Perfect Cell Vs Giblet Episode 1, Giblet appears in the Cell Games Arena, shortly after Cell had destroyed Kermit's newly-bought Xbox Series X (due to the fact that Cell is primarily a fan of the Playstation and PC), wondering what was going on. Both Cell and Kermit are confused about Giblet's identity, jokingly asking if he is just Shallot "going to a dance party" due to his outift, until the annoyed Giblet corrected them. He explained that he was offering them a chance to join his "army", but they (obviously) refused, causing the annoyed Giblet to threaten to kill them, transforming into a Super Saiyan. In response, Kermit asks Cell for some of the power of Budget Increase (as Kermit was temporarily erased from existence for two months) to turn into Super Kermit and challenges the Saiyan to battle.

In Super Kermit Vs Super Giblet (SFM Interactive), a confident Kermit tells Giblet that his chances of winning just went "out the window" and gives him 3 chances to give up. Giblet immediately ignores Kermit and shoots him with a barrage if Ki blasts, but they deal no damage to the muppet. Angry, Giblet attacks him head-on, but Kermit still isn't affected and kicks Giblet away. Frustrated, the ancient Super Saiyan declares he will not be humiliated by morons like Cell and Kermit, and proceeds to insult the DevilArtemis Universe when Kermit tries to persuade the viewers to choose how he will be dealt with. Giblet, realizing what is going on, begs the viewers for mercy, claiming the insult to be just a joke.

Regardless of the viewer's choice, Giblet still meets a horrible fate.

Spare Gibby
If the viewer chooses to spare Giblet, he asks if he won the match by default, only for his claim to be shot down by Kermit, who has their gay friend Zarbon sexually assault him to keep his "promise".

Destroy Gibby
Apparently the canon choice, if the viewers choose to have Giblet killed, Cell and Kermit teleport him to a theater and tie him up to one of the chairs, telling him what will happen next is for the greater good. After teleporting away, the screen starts showing off the terrible movie Dragon Ball Evolution. Knowing how awful the movie is, a screaming, terrified Giblet begs Cell and Kermit to let him out, but they ignore him.

Giblet’s Revenge
At some point after, Giblet, wanting revenge on Cell and Kermit for what they did to him, entered Cell’s Arena during the bio-android’s downtime as Super Saiyan God. When Cell pointed out that he deserved the torment, Giblet angrily claimed that the reason why he even acted like a dick toward Cell, Kermit and the DAU was because Shallot acted like a dick to him first. He reminds Cell of his revenge and the two get into a mock argument about how Giblet will kill him. However, when Giblet tries to take a step, Kermit suddenly appears behind him in his Super Kermit form and promptly beats him up.

Shallot Makes a Wish
After Cell and Shallot accidentally wish for Shenron to make Shallot’s Shark Suit the next “big” thing, Giblet appears wearing a red replica of the Shark Suit (called the "Crimson Shark Suit"), much to Kermit’s shock. Seeing this as another opportunity to gain revenge, Giblet powers up to Super Saiyan God yet again, causing an annoyed Cell to yell out “this is fucking stupid!” However, Shallot, after arguing with Giblet a bit about the originality of the "Crimson Shark Suit", proceeded to just shoot his twin with a bazooka, creating a massive explosion that destroyed Cell's Arena.
