Say Hi to B.U.G!  - B.U.G - Bonded Unity Guardian - He is the creation of Erin in her lab using scrap parts and machinery that she was previously gifted by S.E.R.A.P.H on her birthdays. Spending years working to make B.U.G work, she finished building him when she was 10, and the two have been inseparable family ever since- with B.U.G seeing Erin as his “Big Sister”.

B.U.G is energetic, youthful and a little impulsive, but has his heart in the right place and is fiercely loyal to his big sister Erin. If people try to hurt her, B.U.G will show his teeth and bite viciously into the assailant. He enjoys spending time with Erin at their favorite Matcha cafe, or Erin teaching B.U.G how to draw or skate at the park- but often he cracks his screen from being too excited or clumsy on his feet- leading to him needing repairs more often than not. But when Erin needs him, he rarely falls short as a dependable guardian and loyal little brother.

A loyal best friend and a protective little brother, B.U.G will let no one stand between the bond between him and his big sis. If you plan to hurt Erin, B.U.G will stand in your way bravely to protect her- but often just ends up being the one hurt first. Mentally close to an 8-10 year old, B.U.G tries his best to be a hero, but often him being hurt trying to "save Erin" often leads to Erin hunting down who injured her little brother, before promptly beating the future children out of them.
