Ratchet (Transformers)

Ratchet is a fictional character created by the Transformers franchise. He is a Cybertronian, a fictional extraterrestrial species of sentient self-configuring modular robotic lifeforms (e.g.: cars and other objects), a synergistic blend of biological evolution and technological engineering. He is one of the Autobots, and is their chief medic. His vehicle mode is an ambulance. Named after Nurse Ratched by writer Bob Budiansky, who originally intended the character to be female, an idea rejected by Hasbro. Ratchet is well-remembered by fans of the original comic series, in which he played a major role.

Ratchet would transform into an ambulance (cargo van type) and was colored white with red stripes and emergency lights. Ratchet had two robot modes, though only one was usually seen in the comic run and the television cartoon. The Ratchet toy transformed into the second form. Ratchet was one of the original and the longest-lived of all Transformers in the Marvel Transformers comic series. Often a fan favorite, he was a healer first, but a soldier nonetheless. His courage and loyalty are demonstrated time and again.

Iago PUC's ideas

 * Ratchet is among the featured crossover heroes in Marvel's Spider-Man: Webbed Champion, voiced by Jim Meskimen. Appearing in the crossover arc "Legendary Universes", he and his fellow Autobots (along with the Dinobots and their human allies) first appear in "Part 4: Heroes in Disguise", where they team up with Spider-Man and his team of Champions to defeat Predaking, who was resurrected by crystals powered by Kree technology which was salvaged and discarded by Oscorp's engineers weeks ago and now seeks to convert human technology to his own liking and take revenge on the Decepticons for attempting to enslave him. He is primarily partnered with Arsenal, as Chris Cooper mentions he was once army medic before he was appointed sergeant. Ratchet and the Autobots later appear in "Part 6: Ultimate Alliance", where they join the Avengers and Champions on the battle against the Regent and his army from the Negative Zone. During the battle, he and the genius heroes (BB-8, Miles "Tails" Prower, and Donatello) work alongside Anya Corazon and Hank McCoy / Beast on breaking into Alchemax Labs to hack the control panels and shut the Negative Zone portal down.
 * Ratchet returns in the show's Disney+ sequel miniseries Marvel's All-Star Multiverse, voiced again by Meskimen.
