Dreadeon likes to lure his enemies into the sky where he can take advantage of his strong aerial prowess. With a jagged silhouette of triangles and spikes, Dreadeon is easily recognizable even in the thick of battle. When the blasters on Dreadeon's shoulders are fully activated for battle, his head shifts into optimum fighting position, eagerly anticipating his opponent's next move.
In Mechtogan Mayhem, Razenoid spawned him just like Titanium Dragonoid spawned Zenthon. He was summoned by Razenoid again in Gundalia Under Fire, and the two managed to defeat Zenthon. However, in their rematch in Unlocking the Gate, Dreadeon lost.
In Interspace Armageddon, several different-colored clones of him battled the brawlers. Most of them ended up getting defeated.
Dreadeon is #07 in the series, released in the second wave of Mechtogan. Dreadeon has nine BakuNano port holes. Darkus Dreadeon (either standard or Combat) has 180 Gs. The Darkus McDonalds Dreadeon has 270 Gs.
- Dreadeon was the first antagonist Mechtogan to be seen talking.
- He was shown to have the exact opposite personality to Zenthon. While Zenthon speaks and acts like a Knight, Dreadeon speaks and acts like a savage beast.
- His shoulder spikes are similar to AirKor's bottom wings.
- In a small casting gag, Dreadeon's voice actor is Tony Rosato, the same who voiced Razenoid’s pre-mutated forms Dharak and Phantom Dharak.
- Dreadeon's design seems to be inspired by Orguss 02 from Super Dimensions Century Orguss 02, notably in the shoulders.
