The Hard Boiled Heavies (ハードボイルドヘビーズ), abbreviated as "HBH", are an elite squadron of Eggrobos built by Dr. Eggman who appear in Sonic Mania. The Hard Boiled Heavies themselves were just ordinary Eggrobos that were modified by the mysterious power of the Phantom Ruby they were sent to excavate to represent certain themes and to hold more firepower, though the power seems to have loosened a few of their screws, granting them free will.
During concept stages, Christian Whitehead came up with the Hard Boiled Heavies after imagining Eggman entering depression after the events of Sonic the Hedgehog 3 & Knuckles. Instead of going after Sonic, he would merely lounge about at home wearing his pyjamas, and that a group of abandoned Eggrobos would go "a little mad". The term "Hard Boiled Heavies" came to mind after thinking about this concept.
The Hard Boiled Heavies were first encountered as ordinary Eggrobos who excavated the Phantom Ruby at Angel Island Zone. Throughout Sonic Mania, the Heavies would engage Sonic, Tails and Knuckles in boss battles, usually at the end of Act 2 in place of Eggman (the Heavy Gunner being the exception, as he is fought in Act 1), though each character only gets to fight four of them in a normal playthrough. Much later on in Titanic Monarch Zone, Eggman masters control of the Phantom Ruby and uses it to further transform the Heavies into "Phantom" versions that attack the heroes during the final battle against the Phantom Egg.
After the game's events, the Heavies were defeated and left for scrap at Angel Island Zone. However, the Heavy Magician had survived, and kickstarted the conflict of Encore Mode by swiping the Phantom Ruby from under Sonic and Mighty/Ray's noses and passing it to the Heavy King, reviving the Heavies and repeating most of the events of Mania Mode as bosses.
