Powers and Abilities

At first, Mecha thought he was wearing a suit of alien power armor. Then, he thought he was trapped in a suit of power armor, as there was no way to remove it. Later, he came to the realization that he *is* a suit of alien power armor. There does not seem to be flesh and blood – his body – in the suit anymore, although the skeleton and some organs might remain.

The Mecha suit is strong and tough, can fly quite fast and can extrude energy cannons from its forearms. It has numerous sensors and a very powerful HUD. This later feature contributes to Mecha’s INT, as the environment he sees is clearly labelled and color coded, allowing for enhanced decision taking.



USMC Private Art Thomasson was part of one of the various teams the US Military lost inside the Vortex, sent to their highly probable death in futile attempts to learn more about that phenomenon. Although reported to be dead in action, he was, unknown to the military, one of the very few that actually survived. For him, survival meant merging with the suit of armor originally worn by the alien scientist also called the Vortex when he came to Earth.

The slightly naive and quite altruistic Thomasson went to Golden City, seeing himself as a hero and wanting to associate with other “cool heroes”. Grace allowed it, and he joined the Agents of Change just in the middle of their fight with Warmaker.

He stayed with the Agents until the takeover by Law (whom he never trusted), and was then expelled from the team by Law. Law’s method was rather simple : demonstrate to Mecha he couldn’t hurt him (Law is immune to Vortex-touched abilities), then start killing random persons in the room and telling him he’d only stop slaughtering innocents when Mecha left.

Mecha has steadily increased his skill with the armor, and is now able to use the Power Reserve (at first, it would only trigger due to preprogrammed critical events, such as excessive damage launching the Defensive mode). He also started to have dreams of a powerful alien civilisation of warriors, all wearing armors like his, where “he” underwent rites of passage. This is probably an involuntary access to a sort of audiovisual database of past events.


See illustrations.


Thomasson is a nice, helpful young man who grew up in a loving family in the countryside. A large part of his personality was molded by his term in the USMC : he sees himself as a good soldier, and usually uses military turns of phrase, following orders and the law and trying to act rationally and with tactical acumen.

His view of a super-hero’s role has a bit of the peacekeeping mission of the USMC military police in it.

He sometimes had troubles with the suit feeding him too much information, but he’s now quite fluent with it.


“Take cover ! This area is now a paranormal combat zone !”

“This is restricted airspace. Please leave the area immediately.”

“Im‘ hit… I’m… no flesh. No blood. There’s nobody in my suit. There’s nobody in my suit.”

DC Universe History

Golden City is an interesting theme, and it and its super beings would make an interesting scenario for a JLA adventure. You could also Amalgamate it and the city created by the Ultramarines – a team that Mecha could easily join if you don’t use the whole of Golden City.

Mecha modes

The Mecha suit can change configuration between various modes, altering its look but keeping the same basic theme. This is represented by the Power Reserve. Much of the know-how in the Mecha suit use is knowing how to use modes to their best advantage, and having the necessary stamina and skill to switch between modes.
