Son Goku, the most powerful being in the DBZ Universe, could've died because of a sickness, but got saved after Trunks gave him an antidote/medicine...
SuperMan, the most powerful superhero ever in the DC Universe, thought to be invincible only unless there is not a star that can give him energy...
Onslaught, a combination of the psychic powers of Professor Xavier and the strength of Magneto's abilities - once known as the Universe's Ultimate Threat...
Unicron, most powerful and biggest of all Transformers who is godlike...
Ichigo Kurosaki(Vizard form), ruthless; cunning; destructible and deadly...
Galactos, Devourer of planets, soul-rival of Thanos...
Imagine, all these beings - protectors and threats of the Universe - setup against a cute, blue cat with a shiny bell collar... That is, who can make anything and pull out anything from his pocket, GONE MAD!!!
Nyahahahaha!!!
Doraemon, turning Goku into a baboon!
Doraemon, making SuperMan g*a*y and super sensitive!
Doraemon, disassembling Onslaught into a pile of junk!
Doraemon, transforming Unicron into a toy with pinky colours!
Just imagine how much chaos this guy can do... C'mon guys! Think!
Try to make fun of them uber powerful creations there are(may it be anime or cartoon/comic character) with the possibilities like Doraemon can do to them! I would be most happy to hear your side!
