Only appearing in said concept art, Tabomba never actually made it to the game in any shape or form, in contrast to Achilles, whose unused sprites can be found within Metal Slug 5's code.
- Tabomba appears in the flyer for the PlayStation 2 version of Metal Slug 5.
- He bears a certain resemblance to a portly Mr. Big from SNK's Art of Fighting series of fighting games.
- The fanmade nickname of "Tabomba" is derived from two separate filipino words: taba, meaning "fat", and bomba, which means "bomb".
