Bunsen

Bunsen is a robot who inhabits the city of Robo Land. She is a close friend of Dr. Nerdnick, and may even be his own creation, although her origin was never explained. Bunsen appears to have some sort of artificial intelligence, as she is capable of having conversations with other characters and can think for herself.

Her name originates from the Bunsen burner, a piece of equipment used in laboratories.

''The Super Mario Bros. Super Show!
Bunsen appears only in The Super Mario Bros. Super Show! episode "Robo Koopa". She makes her entrance by extending her arm from offscreen, and uses it to reprogram Robo Koopa's robo-suit when he was attacking Mario, Luigi, Princess Toadstool, and Toad. With Robo Koopa unable to control himself, Bunsen greets Princess Toadstool, whom she had apparently already met at some point prior to the events of the episode.

Bunsen takes Mario's group down a tunnel to Dr. Nerdnick's workshop, explaining that King Koopa had duped Dr. Nerdnick into building him the robo-suit. She then leads them into the workshop, where she is able to free Dr. Nerdnick while the others fight off the Robo Shyguys that guard the place. Eventually Robo Koopa returns. When he cannot get the robo-suit to work properly, Bunsen interprets Dr. Nerdnick's comment, which allows Robo Koopa to capture Princess Toadstool and Toad in force fields. Despite this, Bunsen manages to escape with Dr. Nerdnick, Mario and Luigi,

After a close call, Bunsen and the others eventually escape from Robo Koopa and wind up in a junkyard. In the junkyard, Bunsen helps Dr. Nerdnick assemble the Plumbinator, and cheers Mario and Luigi on as they use it to fight Robo Koopa.

Robo Koopa succeeds in destroying the Plumbinator, and manage to capture Dr. Nerdnick. Bunsen interprets Dr. Nerdnick's next message, telling Robo Koopa to press a particular button on his robo suit in order to stop it from running out of fuel. What she had interpreted was a lie, as the button is for the ejector seat, which sends King Koopa flying out of the robo suit and into the sky.

Afterwards, Bunsen speaks for Dr. Nerdnick, who rewards Mario and Luigi with the robo-suit, which he had converted into a robo pizza oven just for them.

Powers and abilities
Bunsen is capable of extending her arms telescopically, allowing her to reach her target with little difficulty. She can even extend her individual fingers in the same fashion, which is practical for tasks such as pushing numerous buttons. Bunsen is multilingual, as she is capable of understanding the unknown language spoken by Dr. Nerdnick. As such, she is the only known character who understands him and has to serve as an interpreter between him and the other characters. However, Bunsen is programmed to translate anything that Dr. Nerdnick says, regardless of whether or not he wanted other characters to understand him.

Bunsen can also open up her chest plate to reveal an automated screwdriver.
