Limbo Bro.

From the Super Mario Wiki

A Limbo Bro. and its green, stronger version

One of the stranger enemies in Mario & Luigi: Superstar Saga is the Limbo Bro. This giant Koopa Troopa stands on its hind legs and carries a torch. It also sports a helmet of sorts and face paint. It will attack by doing the limbo under its torch and then quickly dashing at its target, or even shooting fire. They make their home in Guffawha Ruins. Teehee Valley has Limbo Bros too, but they're green, and a stronger version. Scorching them with the Firebrand won't do any good since it repleneshes its health.

[edit] Trivia

It is unknown if Limbo Brothers work for Bowser, Cackletta, or are just loners.
