Repugnus and Abomination are a semi-custom I made. I wasn’t satisfied with Repugnus as just a Titan Master, so I took a Transformers Prime: Beast Hunters Lazerback, cut off the neck peg, and glued on a Titan Master adapter I got off Shapeways. I also discovered that a Titan Master can actually fit inside Lazerback in beast mode. So, Lazerback has become Repugnus, and Titan Master Repugnus is now Abomination, a new character. Abomination is one of those ironically-named “odd couple” partners, in that he’s intelligent and refined, despite being paired with — and named — an abomination.
