From the pictures below, can you find the cartoon character?
EDIT: Edited the 3rd picture for clarity
Changing from old to new - one word
Even the highlighted words lead to the answer!!! $$$$
From the beginning I have a feeling of this answer but I don't know how to relate with the first picture.
My guess is, I used to love this cartoon,
The first picture:
Mentioned by OP, it means "accelerate" a.k.a "XLR8". Ben can transform to this alien with his omnitrix.
The second picture:
It's "transform", Ben can transform into 10 (actually more..) aliens. It can also means "upgrade" -- confirmed by OP, one of the alien names.
The third picture:
The comet, where he gets the omnitrix. May also represents aliens or outerspace tho.
The first clue:
I also don't know, Ben is not really a scientist, but Benjamin Franklin is.
The second clue:
Indeed, it is "transform" or "upgrade".
The third clue:
Man of Action Entertainment is the studio making Ben 10.
Spinning a bit further on Udhay's answer, I will try:
Star Blazers, an ABC anime/cartoon show
First image, basically the same reasoning as Udhay:
The Accelerator, Brake and Clutch brake pedals point to ABC
The old seasons where originally released in the early 70ies, while a new remake has been made since 2012.
Literally an image of a Star Blaze.
Not really satisfied with this answer, but I'll give it a shot. The character is:
Captain Comet from DC Comics (also known as simply "Comet"), who was, among other things, an super-intelligent scientist. Although primarily a comic character, he has appeared in Batman: The Brave and the Bold, making him a cartoon character as well.
Playing off others' answers treating this as Accelerator-Brake-Clutch, or ABC: Comet's real name is Adam Blake. Adam-Blake-Comet = ABC
Per Wikipedia, "he occupies an almost unique position in DC Comics history as a superhero who was created between two great superhero comics periods - the Golden Age and the Silver Age"
Comet - pretty obvious
I think the answer is:
As stated by the other answerers, the first image stands for Accelerator Brake Clutch (ABC) which indicates that the cartoon must be broadcasted by ABC (American Broadcasting Company). The Jetsons is broadcasted by ABC.
The Jetsons is the new counterpart to the old The Flintstones, as stated in the Wikipedia article on The Jetsons: "It was Hanna-Barbera's Space Age counterpart to The Flintstones."
Elroy owns a pet called Astro.
Is the answer:(not very sure)
Professor Triffid in Buzz lightyear of star command
As hinted abc by other answers, buzz lightyear of Star command has been broadcast by abc
Old to new: the characters have taken a new look in the Toy story
Stars and comets: prof. Triffid is a scientist(your hint) who researches on planets. The cartoon series is about space rangers.
I thought answer is based on your hint
Dr. Heinz Doofenshmirtz
indicates Accelerator Brake Clutch which is ABC. The Mickey Mouse program was first televised for four seasons, from 1955 to 1959, by ABC(American Broadcasting Company).
indicates Old to New, Dr. Heinz Doofenshmirtz is Evil Scientist (formerly) and new job is High School Science Teacher. So old to new is Scientist to Science Teacher
indicates Disney–ABC Domestic Television
Kinda long shot, but is it
As stated before, Accelerator Brake Clutch - ABC Television
2nd and 3rd photo
From old to new - renovation, 3rd photo is a nova
A show broadcasted by ABC, connected to renovations is Extreme Makeover: Home Edition, which provides home improvements for less fortunate families
Since we are looking for a cartoon character, in relation to EM:HE (improving life quality of less fortunate) my guess is Robin Hood, who "robbed from the rich and gave to the poor" - meaning he also improved life quality of less fortunate
About the 1st hint - Scientist
