Well, Ludwig, I see you have not learned one lesson on composing. Or inventing.
Thomas Koopa

Thomas E. Koopa is a Koopaling, and older than Ludwig. He is an inventor and invented the Lightbulb Goomba. He and Ludwig are rivals, seeing as Ludwig can make good inventions anymore, which is a stupid way to hate someone. He and Iggy are friends, along with Lemmy, Teddy E. Koopa and Bowser Jr. He is 19 years old.


Before he invented the Lightbulb Goomba, Thomas was like all of his siblings: evil. He hated Mario and Luigi, but had a huge rivalry with the Wario Bros. After he invented it, he went a bit crazy. He is now deranged, and tries to create weapons to destroy the Mario and Wario Bros. He is still caring for his siblings, trying to help them at all costs.


He is a bit taller than Iggy. He has three fangs in his mouth and a band-aid over his nostrils. Like Bowser Jr., he has a green head and wears square glasses. His hair is white on the left side and yellow on the right side, and his hair droops behinds his head. He always carries a wooden cane, as his right hip is lop sided. One of his eyes is red, due to an injury with Tim's rock collection.
