Grandfather

**Grandfather** is the main antagonist of *Operation: Z.E.R.O.*. He is a demonic being who ruled the world before being overthrown by his son Monty Uno aka Numbuh 0. Many years later, he is revived by his other son and successor Father and begins transforming the people of the world into Senior Citi-zombies. Grandfather is very tall and lanky, and significantly taller than a normal person. He has a bald head and a large beard with long, scraggly strands of hair. Despite making only one appearance, Grandfather is the most powerful villain in the series.

## Family

* Annoyingly Cute Triplets Who Lived Upon the Hill (mother and aunts)
* Monty Uno A.K.A. Numbuh 0 (elder son)
* Benedict Uno/Father (younger son)
* Mrs. Uno A.K.A. Numbuh 999 (daughter In-Law)
* Numbuh 1/ Nigel Uno (grandson)
* DCFDTL (adoptive grandchildren)

## Personality

Grandfather had no remorse for any of his actions. He betrayed all of the other villains, who were willing to help him, without a second thought and turned them into Senior Citizombies along with the KND. He is also shown to be extremely selfish, wanting the entire world for *himself*simply so that he can have solitude and tapioca pudding, and making the citizombies loyal only to him.

Despite his evil intentions, however, he is shown to be fond of his elder son, Monty (when he's not directly opposing him). Grandfather showed sad disappointment towards the non-evil life his son chose to have. Before Grandfather's decommissioning at the end of Operation Z.E.R.O., it was revealed that despite Monty's rebellion years ago, he was still in Grandfather's will.

Compared to his younger son, however, Grandfather was extremely disappointed with Ben and viewed him as a disgrace and a coward, despite Ben following in his footsteps. He was not pleased nor excited to see him again after his recommissioning, as Ben had not recommissioned him out of love for his father but only so that he could finally defeat the KND.

On top of this, he was not impressed and grew annoyed when Ben points out that unlike Monty, he grew up to be pretty evil, and blasts him in order to make him shut up.

## Powers

Grandfather has the ability to turn people into Senior Citizombies, monstrous, geriatric undead who can turn others into zombies as well, through touch. Although people turned into Senior Citizombies do retain a semblance of their personality, they invariably become the obedient minions of Grandfather and attempt to transform anyone they come in contact with, thus allowing them to rapidly spread. Grandfather's power also affects inanimate objects, making them green-tinted and Victorian in appearance. He can use telekinesis and even shape shifting.

In addition, Grandfather possesses several other superpowers similar to his son, Father, such as his shadow suit, levitation and physical invulnerability. He also appears to be immortal while he has his powers, since not even being crushed by "39 gazillion tons of red hot metal and duct tape" damaged him visibly.

## TMNT X Pokemon

Grandfather is one of the many villains you'll face throughout the game. He's one of the most powerful on the difficulty scale.

## Trivia

* Grandfather was reawakened using the Recommissioning Module, despite not being a member of the Kids Next Door. This implies that he was defeated in the past by a decommissioning device, despite the KND (7th Age/Futuristic that is) not even existing prior to his defeat.
* *Operation: C.A.K.E.D.F.I.V.E.* involves the Annoyingly Cute Triplets Who Lived Upon the Hill, who were enemies of the KND during the nineteenth century. Father refers to the mother of the ACTWLUH as his great grandmother, which would make her Grandfather's Grandmother and one of the triplets is his mother. It is shown in Z.E.R.O. that Numbuh 0 was the founder of the 7th age of the KND and the 19th century was a totally different age.
* Grandfather's large, beaky nose is not visible when his face is shown from the front.
* Grandfather's second rise and fall were both made possible by his sons; Father (Benedict Uno) recommissioned him and Numbuh Zero (Monty Uno) decommissioned him.
* Unlike Father, Grandfather can fly, and his mouth is visible at all times.
* Grandfather's sons and grandson were among the only characters to never be turned into Senior Citi-zombies.
* As Numbuh Zero destroyed the recommissioning module and Grandfather did not show gratitude to Father when he recommissioned him, it is unlikely that he was ever recommissioned. However, it is implied that he regularly pays his son Monty Uno a visit when he does not have his powers.
* Grandfather is the only villain that has not engaged a member of Sector V (Numbuhs 1-5) personally. He is also the only villain to be decommissioned. Furthermore, he is the only villain to actually defeat the KND organization (a Senior Citi-zombified Numbuh 362 personally declares the end of the KND to Grandfather), though he ultimately does not destroy the Book of KND.
* Judging by Father's words during *Operation: I.T.*, it is likely that Grandfather forced his sons to eat broccoli at some point in the past.
* Grandfather's overall design resembled Aku from Samurai Jack.
