Dr. Black, the untold story.

Love him or hate him, Dr.

Thaddeus Black is one of the most notorious personalities Slugterra has

ever seen. As a young man, he dreamed of becoming a top slug slinger. He was

known to bite dirty and would do anything to win, even cheat.

His slugs didn't like that, and neither did his greatest rival, Will Shane.

Finally, someone stepped up to keep Dr.

Black in check.

Until he disappeared.

Dr. Black retired from slug-slinging unrivaled and turned his focus to

science and industry.

He took a broken-down railway system and transformed it into the Slug-Terran

Express, a vast network of lightning-fast trains connecting all but

the most remote caverns. The Express made him rich, but Black still wanted

more. His new goal would be to control all of Slug-Terra, and he created ghouls

to help him do it. That's where we come in.

The Shane Gang have vowed to protect Bugterra and will stop at nothing to

make sure Black and his allies fail.
