Eggman

Dr Ivo Robotniek, more commonly known as Eggman, is a side character on the Tails and Sonic Pals channel. He is voiced by Hype VoiceActing.

Personality
Eggman is a sinister and evil mad scientist of incredible intelligence. Much like his official/canonical counterpart, he is cunning and sneaky, prone to coming up with devious evil schemes to defeat his enemies. However, often his plans are less brazen and more confusing to the main cast. He has also shown some signs of friendship the few times he has hung out with the group, though whether any of this is considered genuine is yet to be seen.

Sonic the Hedgehog
As is the case in the main series, Sonic and Eggman are enemies and don't get along. Eggman has let it be known how much he despises Sonic, yet he usually tries to save grace in any friendly scenarios he finds himself in.

Amy Rose
Amy is the closest thing Eggman has to a friend within the main group. Their relationship could be considered a parallel to how it is in the Sonic Boom series, where they are able to bond over something they share a common interest in - in this instance, cupcake baking. Other characters have voiced there concerns with Amy and Eggman being friends, but so far nothing bad has materialised from it.

Trivia

 * Despite being the main antagonist of the series, Eggman has appeared the least amount of times out of any character in the main cast. In the 2020 Christmas video Tails & Sonic Pals Christmas Special Animatic, he explains that this was because he spent all of that year trolling their channels instead of taking over the world, finding it more enjoyable and cost effective. It is likely, therefore, that this transitioned into the following years as well.
